A car weight 8times more than motorcycle, a motorcycle weight 9 times more than bicycle. If car weight is 1728 than how much is the weight of motorcycle and bicycle.

The motorcycle weighs 216 and the bike weighs 24.

Step-by-step explanation:

C ... car; M... motorcycle; B ... bicycle

C = 1728

A car weight 8 times more than motorcycle. You now make an equation out of this.

C:8=M

1728:8=216

M=216

A motorcycle weight 9 times more than bicycle. You now make an equation out of this.

M:9=B

216:9=24

B=24

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
