Answer 19

To solve for w, let's first isolate the variable on one side of the equation by moving the constant to the other side:

-23 = -3 + 5w

Adding 3 to both sides:

-23 + 3 = -3 + 3 + 5w

-20 = 5w

Now, divide both sides of the equation by 5:

-20/5 = 5w/5

-4 = w

So, the solution to the equation is w = -4.

Answer 20

To solve for u, let's first isolate the variable on one side of the equation by moving the constant to the other side:

-5 = u/2 + 5

Subtracting 5 from both sides:

-5 - 5 = u/2 + 5 - 5

-10 = u/2

Now, multiply both sides of the equation by 2:

-10 * 2 = (u/2) * 2

-20 = u

So, the solution to the equation is u = -20.

7x - 27.

Answer 25

To find the number, we can set up the equation:

x - 17 = -19

Adding 17 to both sides of the equation:

x - 17 + 17 = -19 + 17

x = -2

Therefore, the number is -2.

Answer 26

To find the number, we can set up the equation:

4(x + 4) = 8

Expanding the equation:

4x + 16 = 8

Subtracting 16 from both sides of the equation:

4x + 16 - 16 = 8 - 16

4x = -8

Dividing both sides of the equation by 4:

x = -2

Therefore, the number is -2.

Answer 27

To find the number, we can set up the equation:

x + 4 = 3x

Subtracting x from both sides of the equation:

x + 4 - x = 3x - x

4 = 2x

Dividing both sides of the equation by 2:

2 = x

Therefore, the number is 2.

Answer 28

To find the number, let's set up the equation:

3x + 7 = x - 13

Subtracting x from both sides of the equation:

3x + 7 - x = x - x - 13

2x + 7 = -13

Subtracting 7 from both sides of the equation:

2x + 7 - 7 = -13 - 7

2x = -20

Dividing both sides of the equation by 2:

x = -10

Therefore, the number is -10.

Answer 29

Let's denote the first odd integer as x. Since it is consecutive to the first odd integer, the second odd integer will be x + 2.

The sum of the two consecutive odd integers is given as 40, so we can form the equation:

x + (x + 2) = 40

Simplifying the equation:

2x + 2 = 40

Subtracting 2 from both sides:

2x = 38

Dividing both sides of the equation by 2:

x = 19

So, the first odd integer is 19, and the second odd integer is 19 + 2 = 21.

Therefore, the two consecutive odd integers that sum up to 40 are 19 and 21.

Answer 30

Let's denote the number of women in the Senate as x. Since the total number of members in the Senate is 100, the number of men in the Senate would be 100 - x.

According to the given information, the number of men in the Senate is 4 more than 3 times the number of women. Therefore, we can form the equation:

100 - x = 3x + 4

Simplifying the equation:

100 = 4x + x + 4

Combining like terms:

100 = 5x + 4

Subtracting 4 from both sides:

96 = 5x

Dividing both sides by 5:

x = 19.2

However, since we are dealing with the number of people, x must be a whole number. Therefore, we round 19.2 down to the nearest whole number, which is 19.

So, there are 19 women in the Senate. Substituting this value back into our equation to find the number of men:

100 - x = 100 - 19 = 81

Therefore, there are 81 men in the Senate.

To summarize:
Number of women in the Senate: 19
Number of men in the Senate: 81

Answer 31

Apologies for the incorrect response earlier. Let's recalculate based on the corrected information.

Let's denote the number of women in the Senate as x. Since the total number of members in the Senate is 100, the number of men in the Senate would be 100 - x.

According to the given information, the number of men in the Senate is 4 more than 3 times the number of women. Therefore, we can form the equation:

100 - x = 3x + 4

Simplifying the equation:

100 = 4x + x + 4

Combining like terms:

100 = 5x + 4

Subtracting 4 from both sides:

96 = 5x

Dividing both sides by 5:

x = 19.2

However, since we are dealing with the number of people, x must be a whole number. Therefore, we round 19.2 up to the nearest whole number, which is 20.

So, there are 20 women in the Senate. Substituting this value back into our equation to find the number of men:

100 - x = 100 - 20 = 80

Therefore, there are 80 men in the Senate.

To summarize:
Number of women in the Senate: 20
Number of men in the Senate: 80

Answer 32

Let's denote the distance walked on the first day as x. Since the hikers walked 2.8 mi less on the second day, the distance walked on the second day would be x - 2.8.

According to the given information, the total distance walked is 13.1 mi and it took 2 days. Therefore, we can form the equation:

x + (x - 2.8) = 13.1

Simplifying the equation:

2x - 2.8 = 13.1

Adding 2.8 to both sides:

2x - 2.8 + 2.8 = 13.1 + 2.8

2x = 15.9

Dividing both sides of the equation by 2:

x = 7.95

However, since we are dealing with distance, x must be a whole number. Therefore, we round 7.95 to the nearest whole number, which is 8.

So, the hikers walked 8 miles on the first day. Substituting this value back into our equation to find the distance on the second day:

x - 2.8 = 8 - 2.8 = 5.2

Therefore, the hikers walked 8 miles on the first day and 5.2 miles on the second day.

To summarize:
Distance walked on the first day: 8 miles
Distance walked on the second day: 5.2 miles

Answer 33

Let's denote the page number on one of the facing pages as x. Since the sum of the page numbers on the two facing pages is 937, the page number on the other facing page would be x + 1 (since consecutive page numbers in a book are always one apart).

According to the given information, the sum of the page numbers is 937. Therefore, we can form the equation:

x + (x + 1) = 937

Simplifying the equation:

2x + 1 = 937

Subtracting 1 from both sides:

2x + 1 - 1 = 937 - 1

2x = 936

Dividing both sides of the equation by 2:

x = 468

So, the page number on one of the facing pages is 468. Substituting this value back into our equation to find the page number on the other facing page:

x + 1 = 468 + 1 = 469

Therefore, the page numbers on the two facing pages are 468 and 469.

To summarize:
Page number on the first facing page: 468
Page number on the second facing page: 469

Answer 34

Let's denote the amount of money Marie made as x.

According to the given information:
1. Angie made $20 more than Marie, so Angie made x + $20.
2. Gwen made $27 less than Marie, so Gwen made x - $27.

The sum of the amounts that Angie, Marie, and Gwen made should add up to $140.

Therefore, we can form the equation:

(x + $20) + x + (x - $27) = $140

Combining like terms:

3x - $7 = $140

Adding $7 to both sides:

3x - $7 + $7 = $140 + $7

3x = $147

Dividing both sides of the equation by 3:

x = $49

So, Marie made $49. Substituting this value back into our information to find how much Angie and Gwen made:

Angie made $20 more than Marie:
Angie made $49 + $20 = $69

Gwen made $27 less than Marie:
Gwen made $49 - $27 = $22

Therefore, the distribution of the $140 among the three servers would be as follows:
Angie: $69
Marie: $49
Gwen: $22

Answer 35

Let's denote the depth of the second sea as x.

According to the given information, the average depth of the first sea is four times the depth of the second sea. Therefore, the average depth of the first sea would be 4x.

The difference between the average depths is given as 1308 m. So, we can form the equation:

4x - x = 1308

Simplifying the equation:

3x = 1308

Dividing both sides of the equation by 3:

x = 436

Therefore, the depth of the second sea is 436 meters.

To find the average depth of the first sea, we substitute this value back into our equation:

4x = 4 * 436 = 1744

Therefore, the average depth of the first sea is 1744 meters.

To summarize:
Depth of the second sea: 436 meters
Depth of the first sea: 1744 meters

Answer 36

Let's denote the length of one piece of the board as x cm.

According to the given information, the other piece of the board must be 17 cm longer than the first piece. Therefore, the length of the other piece would be x + 17 cm.

The total length of the board is 75 cm, so we can set up the equation:

x + (x + 17) = 75

Simplifying the equation:

2x + 17 = 75

Subtracting 17 from both sides:

2x = 58

Dividing both sides of the equation by 2:

x = 29

Therefore, one piece of the board is 29 cm long.

Substituting this value back into our equation to find the length of the other piece:

x + 17 = 29 + 17 = 46

Therefore, the other piece of the board is 46 cm long.

To summarize:
Length of one piece of the board: 29 cm
Length of the other piece of the board: 46 cm

Answer 37

Let's represent the lengths of the five consecutive sides of the pentagon as x, x+1, x+2, x+3, and x+4.

The perimeter of a pentagon is the sum of the lengths of its sides.

So, we can form the equation:

x + (x+1) + (x+2) + (x+3) + (x+4) = 65

Simplifying the equation:

5x + 10 = 65

Subtracting 10 from both sides:

5x = 55

Dividing both sides of the equation by 5:

x = 11

Therefore, the lengths of the five sides of the pentagon are:

1st side: x = 11
2nd side: x+1 = 12
3rd side: x+2 = 13
4th side: x+3 = 14
5th side: x+4 = 15

So, the lengths of the sides of the pentagon are 11, 12, 13, 14, and 15.
