Answer:
$23.85
Step-by-step explanation:
39.95 x 3 which can also be 39.95 + 39.95 + 39.95=119.85
So then do 143.70-119.85 to find the answer which is 23.85.
The equation of the line follows the following general structure:

Where m is the slope of the line and b is the y intercept.
Find the corresponding values in the given formula, this way:
In the given equation, m has a value of -1/2, it means the slope is -1/2.
I think the The answer 1/1 or1/2! If it is not correct then ask some one else
Answer:
4pi
Step-by-step explanation:
area of a circle is pi*r^2
and you have diameter of 4
so 4/2 gives radius which is 2
A = pi*2^2 = 4pi
