Step-by-step explanation:
7(x - 3) - (x + 3)(x - 3)
(x - 3)(7 - (x + 3))
(x - 3)(7 - x - 3)
(x - 3)(4 - x)
75, 76, 80, 83, 84, 85, 89, 91, 94, 94
The median is 84.5
You add the two middle numbers (84, 85) and divide by 2.
A % is out of a hundred, so you don't need the %/100. Then, you wouldn't do cross multiplication, you would just divide 15/27. Remember, it would be 15/27 because it's percent markup, not the percent the price increased by. So, doing that simple calculation on a calculator you get 0.5555. This converted to a percent is just moving the decimal to the right twice, or multiplied by a 100. That would give you 55.55%, and that's your answer. Make sense?
Answer:
b = 36
Step-by-step explanation:
27 divided by 6 = 4.5
45 divided by 10 = 4.5
- so, each point was multiplied by 4.5
8 times 4.5 = 36
49.5 is the answer because 66% equals 2/3.
