Answer:
The original price of Toni's hair treatment was $85.
Step-by-step explanation:
From the information given, you know that $72.25 is the price with the 15% discount:
100%-15%=85%
This means that $72.25 representes 85% of the original price and with this, you can use a rule of three to find the price that represents 100%:
72.25→ 85%
x ← 100%
x=(72.25*100)/85
x=85
According to this, the answer is that the original price of Toni's hair treatment was $85.

Answer: ab = 35 Hope this helps, please consider making me Brainliest.
Step-by-step explanation:
If ac = 62, and bc = 27, the remaining length belongs to ab. However, since ac holds bc, subtract ac - bc = ab. Now let's substitute:
ac - bc = ab --> 62 - 27 = ab --> 62 - 27 = 35, 35 = ab

Answer:
q = 6/13, p = 35/13
Step-by-step explanation:
3p + 2q = 9
2p - 3q = 4
_________ (subtract the two equation from each other.)
p + 5q = 5
p = 5 - 5q
2(5 - 5q) - 3q = 4 (substitute value of p into equation)
10 - 10q - 3q = 4
10 - 13q = 4
-13q = -6
<u>q = 6/13</u>
3p + 2(6/13) = 9 (substitute value of q into equation)
3p + 12/13 = 9
3p = 105/13
<u>p = 35/13</u>

The answer is -15
x = -15 because 10+5=15 and 15 + -15 = 0
