## Liv1234 one year ago Need help with checking my answer, I think it's C.

When I do the work, I get an answer of B: $\frac{ 12 }{ 40 } = \frac{ 3 }{ x }$ Set it as a proportion to solve for sides on similar figures

3. MichaelAlex292

x = 10

4. Liv1234

So, you cross multiplied and got 120=12 and then divided and got 10? @MichaelAlex292

5. MichaelAlex292

120 = 12x x = 10 Yes

6. Liv1234

Can you help me with another question?

7. MichaelAlex292

Let me see it first

@sourwing was the first question I posted on here B? I just wanna double check with you. I just wanna be sure.

10. MichaelAlex292

Yep, B is correct, do you need to know why?

11. Liv1234

Well, no I understand since I did out the work. And thank you, but can you help me with that question I just posted? And I understand why C was wrong.

12. MichaelAlex292

For the one you just posted, B is correct: $\frac{ 1 cm }{ 10 ft } = \frac{ 5.2 cm }{ x ft }$ Solve for x

13. Liv1234

So, 52?

14. Liv1234

But is it centimeters or feet?

15. MichaelAlex292

52 ft, Yes

16. Liv1234

Centimeters or feet?

17. MichaelAlex292

ft

18. MichaelAlex292

its converting cm to ft

19. Liv1234

Are you sure? 100%?

20. MichaelAlex292

Yes 100% sure

@Nnesha Can you double check these?
