Answer:
15 rides
Step-by-step explanation:
From the above Question we know that if Tanya goes on a ride, the Algebraic expression = 2x
Where x = number of rides
If Tanya does not play any games, how many rides can she go on?

x = $30/2
x = 15 rides
Hence, if Tanya does not play any games she can go on 15 rides
Answer:
1.5
Step-by-step explanation:

k = 7.5/5 = 1.5
Answer:
11x + 3y
Step-by-step explanation:
7x + 2y + 4x + y
Combine like terms:
7x + 4x 2y + y
11x + 3y
Hope this helps!
