Select the correct answer. What is the justification for step 2 in the solution process?

10x − 25 − 3x= 4x − 1
Step 1: 7x − 25= 4x − 1
Step 2: 7x= 4x + 24
A.
the multiplication property of equality
B.
the division property of equality
C.
the addition property of equality
D.
the subtraction property of equality

Step-by-step explanation:

7x = 4x + 24

3x = 24

x = 8

It is subtraction because you have to subtract 4x from both sides for 3x to be equal to 24. When you subtract 4x from both sides they are making an equation that has variables and numbers isolated to different sides.

The answer is C addition property of equality.

Step-by-step explanation:

In step 1, 7x − 25 = 4x − 1 there are the numbers -25 and -1

In step 2, 7x = 4x + 24 The -25 is removed and -1 is replaced with 24

Meaning that in step 2 25 was added to those numbers meaning the answer C addition property of equality.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
