Answer 1

Use similarity ratios here. The first one will be\[\frac{ 12 }{ 18 }=\frac{ y+2 }{ 24 }\]Cross multiply and solve for y.

Answer 2

12(24)=18(y+2)

Answer 3

288=18y+36
252=18y
14=y

Answer 4

And the second similarity ratio for the x's is this:\[\frac{ 12 }{ 18 }=\frac{ (x-3) }{27 }\]Same thing here...cross multiply.

Answer 5

12(27)=18(x-3)
324=18x-54
378=18x
x=21

Answer 6

tysm!
