Answer 25

Simplify the expression.

0.625 + 3/4

Answer 26

Divide -4/17 and -3/4

Answer 27

h + p + 36

Answer 28

The simplified expression is 2x + (9/4)x + 4.

Answer 29

Apologies for the mistake. The correct simplified expression is (9/4 + 1) x + 4.

Answer 30

To simplify the expression 9/4x + 4 + 2x, we can combine like terms.

The x terms, 9/4x and 2x, can be combined to give us (9/4 + 2)x = (9/4 + 8/4)x = (17/4)x.

So the simplified expression is (17/4)x + 4.

Therefore, the correct answer is D. 11/3x + 4.

Answer 31

To simplify the expression (5y - 1) + (-2y + 4), we can combine like terms.

The y terms, 5y and -2y, can be combined to give us (5y - 2y) = 3y.

The constant terms, -1 and 4, can be combined to give us (-1 + 4) = 3.

So the simplified expression is 3y + 3.

Answer 32

To simplify the expression (3/4x - 1) + (3/4x - 2), we can combine like terms.

The terms with x, (3/4)x and (3/4)x, can be combined to give us (3/4 + 3/4)x = (6/4)x = (3/2)x.

The constant terms, -1 and -2, can be combined to give us (-1 + (-2)) = -3.

So the simplified expression is (3/2)x - 3.

Answer 33

To simplify the expression 7x + 3 (x - 2) - 4x + 8, we use the distributive property to simplify the expression within the parentheses:

3 (x - 2) = 3x - 6

Now we can simplify the entire expression:

7x + 3x - 6 - 4x + 8

Combining like terms:
(7x + 3x - 4x) + (-6 + 8)
6x + 2

Therefore, the simplified expression is 6x + 2.

Answer 34

To simplify the expression (3x - 8) + (2x + 5) - (4x - 8), we need to distribute the negative sign to each term within the third parentheses:

(3x - 8) + (2x + 5) - 4x + 8

Next, we can simplify the expression by combining like terms:

3x + 2x - 4x - 8 + 5 + 8

Simplifying further:
(3x + 2x - 4x) + (-8 + 5 + 8)
x - 3

Therefore, the simplified expression is x - 3.

Answer 35

Apologies for the mistake. Let's try solving it again.

(3x - 8) + (2x + 5) - (4x - 8)

First, let's simplify the expression within the parentheses:

(3x + 2x) + (-8 + 5) - (4x - 8)
5x + (-3) - 4x + 8

Next, let's combine like terms:

(5x - 4x) + (-3 + 8)
x + 5

Therefore, the simplified expression is x + 5.

Answer 36

To simplify the expression 2.2 - 0.5 (0.6x - 1.8), we use the distributive property to distribute the -0.5 to each term within the parentheses:

2.2 - 0.5(0.6x) + 0.5(1.8)

Next, we can simplify the expression:

2.2 - 0.3x + 0.9

Now, combining like terms:

2.2 + 0.9 - 0.3x

Simplifying further:

3.1 - 0.3x

Therefore, the equivalent expression is 3.1 - 0.3x.

Thus, the correct answer is D. 3.1 - 0.3x.

Answer 37

To simplify the expression -6 (1/4x - 2/3x + 5/6x), we need to distribute the -6 to each term within the parentheses:

-6 * 1/4x - 6 * (-2/3x) - 6 * (5/6x)

Next, simplify each term:

-6 * 1/4x = -6/4x = -3/2x

-6 * (-2/3x) = 12/3x = 4x

-6 * (5/6x) = -30/6x = -5x

Now, combine the simplified terms:

-3/2x - 4x - 5x

Combining like terms:

(-3/2 - 4 - 5)x = -3/2x - 9x = -21/2x

Therefore, the simplified expression is -21/2x.

Answer 38

Apologies for the mistake. Let's try solving it again.

-6 (1/4x - 2/3x + 5/6x)

To simplify, let's first find a common denominator for the fractions within the parentheses, which is 12.

-6 (3/12x - 8/12x + 10/12x)

Next, we can combine the fractions:

-6 (-5/12x)

Now we can simplify the expression:

30/12x = 5/2x

Therefore, the simplified expression is 5/2x, which can also be written as 2 1/2x.

Answer 39

To simplify the expression -1/2 (6x + 3), we distribute the -1/2 to each term within the parentheses:

-1/2 * 6x - 1/2 * 3

Next, we can simplify each term:

-3x - 3/2

Therefore, the simplified expression is -3x - 3/2.

Answer 40

To simplify the expression 11 - 9 (-2x - 3), we need to distribute the -9 to each term within the parentheses:

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

Next, simplify each term:

11 + 18x + 27

Now, combine the simplified terms:

18x + 38

Therefore, the simplified expression is 18x + 38.

Answer 41

To factor the expression 35x - 40, we look for common factors of both terms:

Both 35 and 40 are divisible by 5.

So, we can factor out the common factor of 5:

5(7x - 8)

Therefore, the completely factored expression is 5(7x - 8).

Answer 42

To factor the expression 45x - 18y + 36, we look for the greatest common factor (GCF) of all the terms.

The GCF of 45, 18, and 36 is 9.

45x - 18y + 36 can be rewritten as:

9(5x - 2y + 4)

Therefore, the completely factored expression is 9(5x - 2y + 4).

Answer 43

To factor the expression -21x + 28, we look for common factors of both terms:

Both -21 and 28 are divisible by 7.

So, we can factor out the common factor of 7:

7(-3x + 4)

Therefore, the completely factored expression is 7(-3x + 4).

Answer 44

To factor the expression -42k - 54, we can look for common factors in both terms:

Both -42 and -54 are divisible by 6.

So, we can write the expression as:

-6(7k + 9)

Therefore, the equivalent factorization is -6(7k + 9).

Hence, the correct answer is option C: -6(7k + 9).

Answer 45

To factor the expression 100x + 1,000, we look for common factors of both terms:

Both 100 and 1,000 are divisible by 100.

So, we can factor out the common factor of 100:

100(x + 10)

Therefore, the completely factored expression is 100(x + 10).

Answer 46

To simplify the expression 3 - (4x - 5) + 6, we can start by simplifying the expression within the parentheses:

4x - 5

Next, let's simplify the entire expression:

3 - 4x + 5 + 6

Combining like terms:

(3 + 5 + 6) - 4x

14 - 4x

Therefore, the simplified expression is 14 - 4x.

Answer 47

To simplify the expression 3 - (4x - 5) + 6, we can start by simplifying the expression within the parentheses:

-1 * 4x - (-1) * (-5) = -4x + 5

Next, let's simplify the entire expression:

3 - 4x + 5 + 6

Combining like terms:

(3 + 5 + 6) - 4x

14 - 4x

Therefore, the simplified expression is 14 - 4x.

Therefore, the correct answer is A. -4x + 14.

Answer 48

Ella Grace used the expression (5 X 20) + (3 X 20) to calculate the total amount she spent on 5 plants and 3 chairs.

Let's simplify this expression:

(5 X 20) + (3 X 20) = 100 + 60 = 160

Therefore, Ella Grace spent a total of $160 on 5 plants and 3 chairs.

Answer 49

Another expression to calculate the total amount Ella Grace spent on 5 plants and 3 chairs could be:

5 * 20 + 3 * 20

This expression uses the multiplication operator (*) to calculate the total cost of 5 plants and 3 chairs at $20 each.

Answer 50

Apologies for the mistake. You are correct. Another expression to calculate the total amount she spent would be:

(5 + 3) * 20

This expression uses the addition operator (+) to combine the number of plants and chairs, and then multiplies the sum by $20 to calculate the total cost.

Answer 51

The number sentence that represents the area of the entire rectangle using the distributive property is:

(9 * 6) + (9 * 11)

This expression represents the sum of the areas of both rectangles, using the distributive property to distribute the height of 9 to each length.

Answer 52

To simplify the expression 0.625 + 3/4, first, let's convert the decimal 0.625 to a fraction:

0.625 = 625/1000 = 5/8

Now, we can rewrite the expression:

5/8 + 3/4

To add these fractions, we need a common denominator, which is 8.

We can convert 3/4 to have the same denominator:

3/4 = 6/8

Now, the expression becomes:

5/8 + 6/8

Adding the fractions:

(5 + 6)/8 = 11/8

Therefore, the simplified expression is 11/8.

Answer 53

To divide -4/17 and -3/4, we can multiply the first fraction by the reciprocal of the second fraction:

(-4/17) / (-3/4) = (-4/17) * (4/-3)

Multiplying the numerators and denominators:

(-4 * 4) / (17 * -3) = -16 / -51

To further simplify the fraction, we can divide the numerator and denominator by their greatest common divisor (GCD), which is 1:

-16 / -51 = 16 / 51

Therefore, the result of the division -4/17 by -3/4 is 16/51.
