Max spends three times as long on his math homework than he does on his science homework. If he spent total of 64 minutes on mat
h and science homework last night how long did i he spend on homework?
1 answer:
Let X = science homework.
Then math homework would be 3x ( three times as long).
Now you have math plus science = 64 minutes:
x + 3x = 64
Combine like terms:
4x = 64
Divide both sides by 4:
x = 64 / 4
x = 16
He spent 16 minutes on science and 48 minutes on math.
