The rate of change of function A is 7 more than the rate of change of function B.
Mary's backpack: 25% of 65 = 0.25 * 65 = 16.25; 65 - 16.25 = $48.75
Roberto's backpack: 30% of 75 = 0.3 * 75 = 22.5; 75 - 22.5 = $52.5
Mary's backpack was a better buy because it was cheaper.
"Supplementary angles" means "angles add to 180 degrees"
So if x is one angle and 67 degrees is the other, and the two angles are supplementary, then x+67 = 180
The answer is choice A
Factor the side effects of equivalent subtract 9 from both sides of the equivalent take the square root of both sides of the equation subtract 10 from both sides of the equation
Can you be a little more clear, so I can get a better understanding?
