Each U.S. penny weighs 2.5 grams. How many pennies (x) are on a scale if their total weight is 37.5 grams

1 answer:

6 0

All you need to do is divide 37.5 by 2.5. So 37.5/2.5 = 15. Then check your answer and do 2.5 * 15 = 37.5. So the answer is 15 pennies.

A stone is an English measure of weight. There are 14 lb in 1 stone and 2.2 lb in 1 kg.

AveGali [126]

We should use lb to convert weight to kg

let unknown lb be = X
14 lb = 1 stone
X lb = 9 stone
Cross multiply : X × 1 = 9 × 14
X = 126 / 1 = 126 lb

9 stone = 126 lb
let unknown value of kg be = Y
2.2 lb = 1kg
126 lb = Y kg
Cross multiply : 2.2 × Y = 126 × 1
Y = 126 / 2.2 = 57.3 kg

So 9 stone = 126 lb = 57.3 kg
