solve for x

Answer 3

tell me what you get

Answer 4

one sec

Answer 5

x = 5

Answer 6

no

Answer 7

thats incorrect

Answer 8

better

Answer 12

that's the height of the second ramp

Answer 13

thank you

Answer 14

do you know how to do the second part?

Answer 15

no:(

Answer 16

wait do i just double it?

Answer 17

ok you need to solve for y

(5/4)^2 = y/16

Answer 18

1.5625

Answer 19

(5/4)^2 = y/16

(5^2)/(4^2) = y/16

25/16 = y/16

...
...
...

y = ??

Answer 20

confused....

Answer 21

it's not a rational #

Answer 22

25/16 = y/16

25*16 = y*16

400 = 16y

16y = 400

y = ??

Answer 23

oh okay hold on:)

Answer 24

25

Answer 25

ok

Answer 26

yes y = 25

Answer 27

done?
