2.8y + 6 + 0.2y = 5y - 14
(Simplify like terms in first half of equation)
3y + 6 = 5y - 14
(Subtract both sides by 3y)
6 = 2y - 14
(Flip)
2y - 14 = 6
(Add both sides by 14)
2y = 20
(Divide both sides by 2)
y=10
Answer:
The answer is: both class have the same ratio.
Step-by-step explanation:
Get the ratio of tall to short. Divide Tall by Short:
Jack's class:
18/10 = 1.8 tall one for every short one
Michael's class:
54/30 = 1.8
The ratio is the same!
You can further prove this by multiplying 18 times 3 and getting 54, and 10 times 3 and getting 30.

Answer:
a) 25% are bad
b) 75% are good
Step-by-step explanation:
We know that there are 300 oranges total and that 75 are bad. That means that the rest are good (implied).
300 - 75 = 225 good oranges.
So to find the percentage we have to take the selected amount divided by the total amount.
Bad Apples: Good Apples:
75 / 300 = 0.25 225/300 = 0.75
However, that's a decimal or <em>a number out of 1, </em>we need a percent or <em>a number out of 100.</em> So we have to multiply both numbers by 100.
Bad Apples = 25%
Good Apples = 75%
