What is b in this equation?
6 + 4/5 = 9/10 b

the answer is 68/9.

STEP BY STEP: 6+4/5=9/10B

combine like terms (6+4/5)

34/5 = 9/10B

flip the equation

9/10B = 34/5

multiply both sides by 10/9

(10/9)(9/10B) = (10/9)(34/5)

and then you get your answer, which is stated above! :)

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
