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


2.5 + x = 37.5

x = 35


2.5 x = 37.5

x = 35


x - 2.5 = 37.5

x = 40


2.5 x = 37.5

x = 18


Please help!

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.
