25 points to anybody who can solve this pls!
Svetach [21]

Answer:

Q' (2,4)

R' (3,1)

S' (5,3)

1. Avital counted 40 green cars and 20 silver cars in the parking lot. If the number of green cars stay the same, how many more
Luba_88 [7]
X represents the number that would be added to the silver cars.


x/40= 4
X=40x4
x=160

Subtract the given 20 from 160 because 160 is the total number
160-20=140
Therefore 140 would be added to 20 silver cars to get the ratio1:4
