Answer:
Which are equivalent expressions?
Check all that are true.
y + x = 2x
x + x + x + x = 4x (true)
x + x = 2x (true)
x + y + y + x = 2x + 2y (true)

Answer:
11 hours
Step-by-step explanation:
let he works at first store x hours and at car wash y hours. Then
x+y=25
multiply by 4
4x+4y=100 ...(1)
12x+15y=333
divide by 3
4x+5y=111 ... (2)
(2)-(1) gives
y=111-100=11
