First, simplify the expression within the parentheses:

1 - 15 = -14

Next, divide -14 by 4:

-14 ÷ 4 = -3.5

Now, multiply -2 by -3.5:

-2 × (-3.5) = 7

Finally, subtract 7 from 13:

13 - 7 = 6

Therefore, the simplified expression is 6.

Apologies for the mistake. Let's simplify it again:

First, simplify the expression within the parentheses:

1 - 15 = -14

Next, divide -14 by 4:

-14 ÷ 4 = -3.5

Now, multiply -3.5 by -2:

-3.5 × (-2) = 7

Finally, subtract 7 from 13:

13 - 7 = 6

Therefore, the simplified expression is 6.

Let's simplify the expression again:

We have 13 - 2(1 - 15) ÷ 4.

First, within the parentheses, we have 1 - 15 = -14.

Next, we divide -14 by 4: -14 ÷ 4 = -3.5.

Now, we multiply -3.5 by 2: -3.5 × 2 = -7.

Finally, we subtract -7 from 13: 13 - (-7) = 13 + 7 = 20.

So, the simplified expression is 20. Therefore, the correct choice is 20.

To solve for x in the equation -5x + 2 = 67, we want to isolate x on one side of the equation.

First, let's get rid of the constant term on the left side by subtracting 2 from both sides:

-5x + 2 - 2 = 67 - 2

This simplifies to:

-5x = 65

Next, we want to get x alone on one side of the equation. To do this, we divide both sides by -5:

(-5x) / (-5) = 65 / (-5)

This simplifies to:

x = -13

Therefore, the solution to the equation is x = -13.

To solve for r in the equation r/5 - 6 = -1, we want to isolate r on one side of the equation.

First, let's get rid of the constant term on the left side by adding 6 to both sides:

r/5 - 6 + 6 = -1 + 6

This simplifies to:

r/5 = 5

Next, we want to get r alone on one side of the equation. To do this, we multiply both sides by 5:

(r/5) * 5 = 5 * 5

This simplifies to:

r = 25

Therefore, the solution to the equation is r = 25.

To solve for x in the equation -3x - 8 = 10, we need to isolate x on one side of the equation.

First, let's get rid of the constant term on the left side by adding 8 to both sides:

-3x - 8 + 8 = 10 + 8

This simplifies to:

-3x = 18

Next, we want to get x alone on one side of the equation. To do this, we divide both sides by -3:

(-3x) / -3 = 18 / -3

This simplifies to:

x = -6

Therefore, the solution to the equation is x = -6.

To simplify the expression (2x + 2) - (3x + 11), we need to distribute the negative sign to both terms inside the parentheses:

2x + 2 - 3x - 11

Next, combine like terms:

(2x - 3x) + (2 - 11)
-x + (-9)

Therefore, the simplified expression is -x - 9.

To solve the equation 20 = 6x - 4, the first step is usually to isolate the variable term (the term containing x) on one side of the equation.

In this case, we can add 4 to both sides of the equation:

20 + 4 = 6x - 4 + 4

This simplifies to:

24 = 6x

Now, the variable term (6x) is isolated on one side of the equation, so we can proceed to solve for x by dividing both sides by 6.

(24)/6 = (6x)/6

This simplifies to:

4 = x

Therefore, the solution to the equation is x = 4.

To simplify the expression 6(3x - 5) + 2(3x - 5) - 8(2x - 5), we can distribute the numbers outside the parentheses to the terms inside.

Starting with 6(3x - 5):
6 * 3x = 18x
6 * -5 = -30
So, 6(3x - 5) becomes 18x - 30.

Next, distributing 2 to (3x - 5):
2 * 3x = 6x
2 * -5 = -10
So, 2(3x - 5) becomes 6x - 10.

Lastly, distributing -8 to (2x - 5):
-8 * 2x = -16x
-8 * -5 = 40
So, -8(2x - 5) becomes -16x + 40.

Now, the simplified expression is:
18x - 30 + 6x - 10 - 16x + 40.

Combining like terms, we have:
18x + 6x - 16x - 30 - 10 + 40.

Simplifying further, we get:
(18x + 6x - 16x) + (-30 - 10 + 40).
(-8x) + (0).
-8x.

Therefore, the simplified expression is -8x.

Apologies for the mistake in the previous response. Let's simplify it again:

Starting with 6(3x - 5):

6 * 3x = 18x
6 * -5 = -30

So, 6(3x - 5) becomes 18x - 30.

Next, distributing 2 to (3x - 5):

2 * 3x = 6x
2 * -5 = -10

So, 2(3x - 5) becomes 6x - 10.

Lastly, distributing -8 to (2x - 5):

-8 * 2x = -16x
-8 * -5 = 40

So, -8(2x - 5) becomes -16x + 40.

Now, the simplified expression is:

18x - 30 + 6x - 10 - 16x + 40.

Combining like terms, we have:

(18x + 6x - 16x) + (-30 - 10 + 40).

This further simplifies to:

8x + 0.

Therefore, the simplified expression is 8x.

Let's write the equation and solve for the unknown number.

Let's assume the unknown number is represented by the variable "x".

The statement "Twice a number, increased by 3 is 7" can be written as:

2x + 3 = 7

Now, we can solve for x by isolating the variable.

Subtract 3 from both sides:

2x + 3 - 3 = 7 - 3

This simplifies to:

2x = 4

Finally, divide both sides by 2 to solve for x:

(2x) / 2 = 4 / 2

This simplifies to:

x = 2

Therefore, the unknown number is 2.

To solve for x in the equation 3x - 7 - 2x + 5 = 6, we want to simplify and isolate x on one side of the equation.

First, combine like terms:
(3x - 2x) + (-7 + 5) = 6
x - 2 = 6

Next, isolate x by adding 2 to both sides:
x - 2 + 2 = 6 + 2
x = 8

Therefore, the solution to the equation is x = 8.

If the temperature in Atlanta was -2°F in the morning during the winter and then dropped 10 degrees, we need to subtract 10 from -2°F to find the new temperature.

-2°F - 10°F = -12°F

Therefore, the temperature now is -12°F.

Shawn is multiplying both sides of the equation by 7 in order to eliminate the denominator of 7 in the expression (x/7) on the left side. By doing this, he can simplify the equation and solve for x more easily.
Answered by GPT 3.5
Apologies for the confusion in my previous response. Shawn is not adding or subtracting the denominator. In order to eliminate the denominator of 7 in the expression (x/7) on the left side of the equation, he is actually multiplying both sides of the equation by 7. This helps simplify the equation and allows him to isolate the variable x and find its value.

To calculate how much the climber needs to descend to return to his original starting point, we need to find the difference between the total amount he climbed and the total amount he descended.

The climber starts at an elevation of 380 ft and climbs 182 ft at the first rest stop, and then climbs another 208 ft at the second rest stop. Therefore, the total amount he climbed is:
380 + 182 + 208 = 770 ft.

If the climber now descends 235 ft, we subtract this from the total climbed:
770 - 235 = 535 ft.

Hence, in order to return to the original starting point, the climber needs to descend 535 ft.

To solve this problem, we can set up an equation based on the given information.

Let's assume the regular price of each ticket is represented by the variable "x."

Since Dea buys 6 tickets and the total cost is $51, we can set up the equation:

6(x - 1.50) = 51

Next, we can simplify the equation:

6x - 9 = 51

To isolate the variable term, we add 9 to both sides of the equation:

6x - 9 + 9 = 51 + 9

This simplifies to:

6x = 60

Finally, to solve for x, we divide both sides by 6:

(6x)/6 = 60/6

This simplifies to:

x = 10

Therefore, the regular price of each ticket is $10.

To solve for x in the equation (1/3)(6x - 9) = -11, we will multiply both sides of the equation by 3 to eliminate the fraction:

3 * (1/3)(6x - 9) = 3 * (-11)

This simplifies to:

6x - 9 = -33

Next, add 9 to both sides of the equation to isolate the variable term:

6x - 9 + 9 = -33 + 9

This simplifies to:

6x = -24

Finally, divide both sides of the equation by 6 to solve for x:

(6x) / 6 = (-24) / 6

This simplifies to:

x = -4

Therefore, the solution to the equation is x = -4.

To solve for x in the equation (3/5)(15x - 30) = 198, we will multiply both sides of the equation by 5/3 to eliminate the fraction:

(5/3)(3/5)(15x - 30) = (5/3)(198)

This simplifies to:

15x - 30 = 330/3

Next, simplify the right side of the equation:

330/3 = 110

Now, add 30 to both sides of the equation to isolate the variable term:

15x - 30 + 30 = 110 + 30

This simplifies to:

15x = 140

Finally, divide both sides of the equation by 15 to solve for x:

(15x) / 15 = 140 / 15

This simplifies to:

x = 140/15

The simplified value of x is not a whole number, so x ≈ 9.333.

Therefore, the solution to the equation is x ≈ 9.333.

Now, add 30 to both sides of the equation to isolate the variable term:

15x - 30 + 30 = 110 + 30

This simplifies to:

15x = 140

Finally, divide both sides of the equation by 15 to solve for x:

(15x) / 15 = 140 / 15

This simplifies to:

x = 140/15

The simplified value of x is approximately 9.333, but in the given choices, none of the options matches.

To solve for x in the equation 3(4x - 12) = 84, we will simplify and isolate the variable.

First, simplify the equation by distributing 3 to the terms inside the parentheses:

3 * 4x - 3 * 12 = 84

This simplifies to:

12x - 36 = 84

Next, isolate the variable term by adding 36 to both sides:

12x - 36 + 36 = 84 + 36

This simplifies to:

12x = 120

Finally, solve for x by dividing both sides by 12:
