Problem 4: B

Problem 6: B

Problem 5: B

Problem 3: A

problem 7: A

Step-by-step explanation:

For Problem 4:

5x-8y+3=5x-7y+2

5x-8y+3-5x+7y-2=0

We combine like terms: All of the variable terms and constants

0x-y+1=0

-y+1=0

-1(-y+1)=0(-1)

y-1=0

B is the answer.

For Problem 6:

The absolute value of C is 6. The absolute value of D is 7.

We can write an equation:

2(6)+3(7)

=12+21

=33

B is the answer.

For Problem 5:

w/5=25

w=25*5

w=125

B is the answer.

For Problem 3:

The absolute value of B is 7 and the absolute value of A is 3.

7-3=4

A is the answer.

For Problem 7:

5k=35

Divide each side by 5

k=7

The answer is A.
