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.

A university president's salary for 2012-2013 academic year was $452,000. Calculate his 2013-2014 salary if he received a 2.8% raise
452,000×1.028=464,656
-2
Step-by-step explanation:
x^2 = 5 + (1/2)x
x^2 - 0.5x - 5 = 0
x = 5/2
x = -2
