10 is the amount of video game you need to rent to equal each other
Step-by-step explanation:
Video store A is 8x
Video store B is 3x+50
8x = 3x +50

x= 10
The least common denominator of 12, 8, and 36 is 72.
Hey there, Alex!
She would expect 55 of them to be left handed.
Work: 550 / 20 = 27.5
27.5 x 2 = 55
Hope I was able to help!
Answer:
2x+10=-8
x=9
3x=9
x=3
2x=8
x=4
4x=20
x=5
Step-by-step explanation:
Answer:
4:1
Step-by-step explanation:
x+20 : y+20 = 5 : 2
(x+20)/(y+20) = 5/2
2(x+20) = 5(y+20)
2x+40 = 5y+100
2x = 5y+60 (1)
x-5 : y-5 = 5:1
(x-5)/(y-5) = 5/1
x-5 = 5(y-5)
x-5 = 5y-25
x = 5y-20 (2)
Solve (1) & (2) simultaneously,
2(5y-20) = 5y+60
10y-40 = 5y+60
5y = 100
y = 20
x = 5y-20
x = 5(20)-20 = 100-20
x = 80
x:y
80:20
4:1
