Answer:
Question 1 : B) (8 x 20) - (8 x 1)
Question 2 : D) (2 x 9) + (2 x 3)
Step-by-step explanation:
Distributive Property is used in algebraic expressions, to divide the equation, to make it easier to solve. For question 1, since it was 20, you must subtract 8 from that answer, because 20 is 1 more than 19. For question 2, (2 x 9) + (2 x 3) would be the same thing as 2(9+3).

Answer:
B) (8 x 20) - (8 x 1)
D) (2 x 9) + (2 x 3)
Step-by-step explanation:
Distributive Property: "The distributive property tells us how to solve expressions in the form of a(b + c)."
___________________
Step 1: 8 x 19 = 152
Using PEMDAS, you can see which order to solve the equations in.
PEMDAS tells us to solve whatever is within the parenthesis first but there are 2 parenthesis and both have multiplication so just solve the first parenthesis first;
8 x 20 = 160
Step 2: We now have to solve the second parenthesis;
8 x 1 = 8
Step 3: Using PEMDAS, we see that after we solve the parenthesis, we do subtraction. So subtract 8 from 160.
160 - 8 = 152
So your answer is B) (8 x 20) - (8 x 1).
___________________
Step 1: 2(9 + 3)
Using the Distributive property, we multiply 2 by 9 and 3;
2 x 9 = 18
2 x 3 = 6
Now you are left with 18 + 6.
18 + 6 = 24
So your answer is D) (2 x 9) + (2 x 3).

Answers
Answer:
x° = 107°
Step-by-step explanation:
Given that m < 107° and m < x° are alternate interior angles that do not have a common vertex on alternate sides of the transversal, then it means that they have the same measure. It also implies that their supplements will have the same measure, 73°.
Therefore, x° = 107°.

Kylee is making a cake. The box says for every 1/4 cup of water she needs to use 2/4 of the cake mixture. She uses 3 1/4 cups of water. How much cake mixture does she use? (show your answer as a decimal and as a fraction.)
Answers
Answer:
Kylee makes 6 1/2, or 6.5 cups of the cake mixture.
Step-by-step explanation:
She uses double the cake mixture as water. She uses 3 1/4 cups of water, or 13/4 as an improper fraction, so she uses double that of cake mixture, which is 6 1/2, or 26/4 cups of cake mixture.
As a decimal that is 6.5.

Recall that the perimeter of a rectangle is P=2(W+L), where W is the width and L is the length. The length of a rectangle is 23 feet more than the width. If the perimeter is 70 feet, then what is the length of the rectangle, in feet?
Answers
Answer:
Length = 6 + 23 = 29 feet
Step-by-step explanation:
Width = x
Length = x + 23
2x + 2(x+23) = 70
2x + 2x + 46 = 70
4x = 70-46
x = 24/4

Associative Property of Addition
Step-by-step explanation:
According to the Associative Property of Addition: when three real numbers are added, it makes no difference which two are added first.
a + (b + c) = (a + b) + c
Therefore, in the given equality statement: (6 + 4) + 100 = 6 + (4 + 100), the sum of the numbers on either side of the equation will have the same results.
(6 + 4) + 100 = 6 + (4 + 100)
(10) + 100 = 6 + (104)
110 = 110
