If a = -15, b = 5 and c = -2
a - b - c = -15 - 5 - (-2)
= -20 + 2
= -18
to evaluate 5 squared you must simply do 5x5. Which equals 25.

explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
The answer is x = 5. There is nothing to evaluate there!

6 + 12 - 5 = 13
Its evaluation is: (4*5)+(7*3) = 41
(3 * 3)(2 * 5) (9)(10) 90
2/5 plus 1/15 equals 6/15+1/15 equals 7/15.

Evaluate 9p + 33 for p = 5
It equals 88 10/3 = 50/15 12/5 = 36/15 3 and 1/3 - 2 and 2/5 = 14/15
