Commutative Property of Multiplication
Algebra: What is the markup price of a shirt if it costs $45 with 25% markup?
Algebra: $56.25
Simplify: -4(3x - 2) -2(4 + 3x)
-18x
What does slope represent?
the "change in x" over the "change in y"
What property is shown: (a * b) * c = a(b * c)
Associative Property of Multiplication
Algebra: Evaluate for a:
2(2 + 3x) - 3(7 - 4x) + 5a - 2a = 0
Algebra: a = 17/3-6x
Solve for a: ax + b = y
a = (y - b)/x
Distribute and solve
-9 (-3x + (-7)) = 117
x = 2
Simplify: 4h2k - 4hk2 + 2k2 + 7hk2 - 3h2k - 3hk2
2hk + 4k
