Answer:
I believe he can go on 30 rides.
Step-by-step explanation:
The equation would be 5 + .5x = 20
Because $5 to get in, plus $.50 per ride (x is number of rides you are solving for), and $20 is total amount you can spend.
So, .5x=15 so x=30
As the exercise says, the triangles are similar. So, we can set up proportions between correspondent sides.
In order to solve for x we can set up the proportion between the horizontal and vertical sides:

Solving this proportion for x implies 
Now you can solve for m and p using the pythagorean theorem, because both triangles are right:

Then, we know that the hypothenuse of the big triangle is m+p, so we have

which implies

Answer:
the number would beeeeeee 14
Here’s the answers , it stops at 7 in the picture but here’s 8-9
8. Statement - m<1+m2=m<3+m<1
Reason - substitution property
9. Statement - m<2 = m<3
Reason - subtraction property
10. Statement - <2=<3
Reason - definition of = angles !!
