Answer:
15%
Step-by-step explanation:
Given,
Original price = $55.00
Discounted price = $46.75
Discount = $55.00 - $46.75 = $8.25
Percent Discount = (Discount / Original price) x 100%
= (8.25 / 55.00) x 100%
= 0.15 x 100%
= 15%
Answer:
Step-by-step explanation:
3(x+7)=-36
x+7=-12
x=-19
The first step you should do is subtract 32 from both sides so your answer will turn out like this -
F = (9/5) C + 32
-
F - 32 = (9/5)
Then we will multiply both sides by 5.
5 ( F - 32 ) = 9 C
Divide both sides by 9 to isolate C.
(5/9) ( F - 32 ) = C
So the answer is :
C = (5/9) ( F - 32 )
Hope this helps :)
