Answer 5

these are proportions...

2/3 = 1.2/x
cross multiply
(2)(x) = (1.2)(3)
2x = 3.6
x = 3.6/2
x = 1.8

any questions about this one ?

Answer 12

Yeah

Answer 13

I have 1 question...is the problem 4/5 = (8/x) + 2 or is it
4/5 = 8/(x + 2) ??

Answer 14

well it's 8 over x+ 2

Answer 15

4/5 = 8/x + 2
cross multiply
4(x + 2) = (5)(8)
4x + 8 = 40
4x = 40 - 8
4x = 32
x = 8
