The correct formula would be C
multiply principle ( $800) by (1+interest rate as a decimal) to the power of number of years
so you would have 800 x (1+0.03)^7
Assume the radius is R.
2*pi*R = 28 -> R = 14/pi
So the area will be pi*R^2 = 196/pi
Answer:
20%-X=a
Step-by-step explanation:
So if there is a toy that cost $50 and it was 20% off it would then cost $40
You have zero terms in that equation. A term is when a number is connected to a variable. You have no variables.

they are the same so set them equal
3x-10=2x+40 now combine like terms
3x-2x=40+10
x=50
