3x + 5x = 10

Which problem begins the same way?
A) 5x = 20
B) 2(x + 5) = 20
C)
x
4
= 30
D) 4x − 2x = 10

ok

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

i’m here for points.
