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:
4.64
Step-by-step explanation:
You multiply 2.32 by 2
2.32*2 = 4.64
Answer:
We know that the angles of a triangle always add up to 180 degrees, and we also know that this triangle is congruent because it has the two dashes on the side of the triangle. We also know that x is 90 degrees but this is not drawn to scale but we can just assume it is 90 degrees.
We can tackle the triangle on the right first subtracting 47 and 90 from 180 which will give us the angle y as angle DAC is congruent to angle BAC.
180-47-90=43.
We also know that angle x is 90 degrees already or at least we assume so but to further prove our point we know that angle BCA is congruent to angle CBA which makes angle CBA 47 degrees, so subtracting 43 and 47 from 180 we have 90 degrees.
Therefore y is 43 degrees and x is 90 degrees.
it's kinda confusing ngl
*assuming that x is a right angle
