Let x represent the number of half-gallons purchased by the store. Then x-13 is the number sold, and 2.80x is the store's cost. The revenue is 4.06(x-13) and the difference between that and cost is the profit.
... 4.06(x -13) -2.80x = 63.14
... 1.26x - 52.78 = 63.14 . . . . eliminate parentheses, collect terms
... 1.26x = 115.92 . . . . . . . . . . add 52.78
... x = 115.92/1.26 = 92 . . . . . divide by the coefficient of x
The store purchased 92 half-gallons of milk.
Answer:
to get the area of a circle, you do pie times radius squaared, so we divide 4 to get the radius. so 2*2 is the radius squared,so now we just times 4 by 3.14= 12.56
so the area= 12.56 inches!

Answer:
48 degrees
Step-by-step explanation:
First, calculate the supplementary angles for 99 degrees and 129 degrees. You would get 81 degrees and 51 degrees respectively.
Then add those two numbers and you'll get 132 degrees. Since a triangle equals 180 degrees, use: x + 132 = 180. You would get x as 48.
