In triangle rst,
if tx = 3, xr = ty, and
ys = 6, find xr.

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The triangle RST and the triangle XYT are similar

then

the ratio of their corresponding sides are equal  

substitute the values

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
