Answer:
5x=5(20)=20 for Ed
2x=2(20)=40 for pete
together they had 140 cars
Step-by-step explanation:
5:2 is the ratio
5x-30=2x+30 tat when Ed gave Pete 30 cars
solve for x
5x-2x=30+30
3x=60
x=20
substitute for x: 5x=5(20)=20 for ED
2x=2(20)=40 for pete
The correct answer is (2g2 - 3) • (4g + 5)
A. 2x3=6 and 6x12=72 so 78 is greater than 36
6+72=79 which is less than 90

ANSWER
Find out the how many cans does each one have.
To proof
As given
Amelia and Elliott are collecting empty soda cans for recycling
Amelia has 13 less than 5 times the cans that Elliott has.
let us assume that the Elliott has can be =x
Amelia can = 5x -13
Total can = 257 cans
than the equation becomes
x + 5x - 13 = 257
6x = 257 +13
6x = 270
x = 45
Elliott has can be = 45cans
Amelia can = 5 × 45 - 13
= 212cans
Hence proved
