Question

One of the steps Jamie used to solve an equation is shown below. -5(3x + 7) = 10 -15x +-35 = 10 Which statements describe the procedure Jamie used in this step and identify the property that justifies the procedure?

AJamie multiplied 3x and 7 by -5 to eliminate the parentheses. This procedure is justified by the associative property.
B Jamie added -5 and 3x to eliminate the parentheses. This procedure is justified by the associative property.
C Jamie multiplied 3x and 7 by -5 to eliminate the parentheses. This procedure is justified by the distributive property.
D Jamie added -5 and 3x to eliminate the parentheses. This procedure is justified by the distributive property.​

Answer 1

The correct answer is C: Jamie multiplied 3x and 7 by -5 to eliminate the parentheses. This procedure is justified by the distributive property.

Explanation:
In the given step, Jamie multiplied each term inside the parentheses (3x and 7) by -5. This multiplication is performed to distribute the -5 to both terms within the parentheses, resulting in -15x and -35. This procedure is justified by the distributive property, which states that when a number is multiplied by a sum or difference inside parentheses, it can be distributed to each term within the parentheses.
