Maya bought 3 cds that were each the same price. including sales tax, she paid a total of $ 47.70 . each cd had a tax of $ 1.10 . what was the price of each cd before tax? $

47.70- 3.30=44.40

44.40/ 3=14.80

each cd cost 14.80

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
