Let A, M, and w represent Angelo's distance per week, Marc's distance per week, and the number of weeks of this regimen, respectively.
.. A = w +7 . . . . . . . Angelo's distance goes up 1 mile/week each week
.. M = 2w +4 . . . . . Marc's distance goes up 2 miles/week each week
a) A = M
.. w +7 = 2w +4
.. 3 = w . . . . . . . . . . subtract w+4
After 3 weeks Angelo and Marc will be running the same distance.
b) A = M = 3+7 = 2*3+4 = 10
That distance will be 10 miles per week.

This problem can be a little confusing because "miles per week" is a rate, and we're talking about the rate of increase of that rate: 1 or 2 miles per week per week. It might be easier to think of the numbers as "weekly distance", rather than "miles per week".
Using formula: <span>A=Pi*r^2
A would represent the area of the whole mural but we would plug in r as 25, 50 is the whole width half of it is 25 which is the radius. the whole circle has a degree of 360 but we need the area of 38 degree.</span><span>
A=38/360*pi*25^2
=16.57</span>
Answer:
a. True.
Step-by-step explanation:
y = kx
y = 2 when x = 8 gives:
2 = 8 * k
k = 2/8 = 1/4.
It would take 3 bottles. 25 twelve-ounce cups equals out to 300 ounces. There is only 128 ounces in a gallon.
-7/6 is the answer hope it helped
