X= purchase price

Multiply purchase price by sales tax % to equal the amount of sales tax.

(8.75% * x)= $15.75
convert % to decimal (8.75% ÷ 100)

0.0875x= 15.75
divide both sides by 0.0875

x= $180.00 purchase price

ANSWER: The purchase price is $180.00 (to nearest cent).

In a triangle, the measure of one angle is five more than the first and the third angle is one more than four times the first.

katrin [286]

Answer:

A= 29

B=34

C=117

Step-by-step explanation:

A triangle has three sides and a triangle always adds up to be 180

A + B + C = 180

B = A + 5

C = 4A + 1

Plug in.

A + A + 5 + 4A + 1 = 180

6A + 6 = 180

6A = 174

A = 29

Now since you found A, find the other two by plugging A in!

C = 4(29) + 1

C = 117

Plug in the B equation

B = 29 + 5

B=34

Check your answers

29 + 117 + 34 = 180
