Azul bought 10 reams of paper at the store for $84. The tax on the purchase is $4. What was the cost of each ream of paper. Which equation can you use?
10r + 4 = 84
10r - 84 = 4
4 ( 10r) = 84
4 - 10r = 84

The answer is 10r-84=4

Step-by-step explanation:

answer:

your answer is: c. 196 7/8 in^3.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
