What is the slope of the following equation:
2x + 2y = 8
slope = -1
is 555,098,784,832 divisible by 8? explain
yes, because 832 is divisible by 8
Simplify: a(b - c) - 2a(c + b)
-1ab - 3ac
Algebra: Solve for a: ax + b = c
Algebra: a = (c - b)/x
Solve: (3 - 3x)/7 = 6
x = -13
Evaluate: {[(2 * 3) + (7 * 4)] + 2} * [(8 - 6) - (4 - 3)]
