**Algebra**

Don't be scared by word problems...just take what you know and plug it into an equation. Twice as long for history as psych, so psych will be X and history will be 2X. You know the total is 12 hours, therefore the equation will be 2X + X = 12. Combine like terms...3X = 12...

**math**

This looks to me like a fraction. The numerator would be 36+9 and the denominator would be 3x5. The answer would be 45 / 15, which is really just a division problem 45 divided by 15 which would give you an answer of 3.
