X/3 -2 = 5x-2 (multiply by 3)
x-6=15x-6
x=15x
14x=0
x=0
Answer:
Step-by-step explanation:
You have it right it is 6^x -3
What is 7x30 = 7 x --- tens = --- tens = ---
The original price of the hat is $35. Paolo paid $28 for the hat.
So discount for the hat is $(35-28) = $7
$7 is discounted from $35. We have to find the percentage of the discount.
To find the percentage we have to divide the discount amount by the original price and then have to multiply it by 100.
So the discount percentage =
((7/35)×100) %
We can simplify 7/35 by dividing 7 and 35 both by 7. So we will get 1/5 after simplifying.
((1/5) ×100) %
(100/5)% = 20%
So the hat was discounted by 20%.
