First, you need to find how much money the tax was (98.90-92=6.9) Then, divide the tax by the price without the tax to find the tax rate (6.9/92=.075) then multiply the answer by 100 (.075*100=7.5)The tax rate is 7.5%
Since its multiplication you don't have to have a common denominator so you multiply straight across. The answer is 48/36.
Answer:
Two negatives make a positive.
Step-by-step explanation:
Hi!
First find how much you were off by.
14-12=2
Now set up a proportion and cross multiply to solve.

2 x 100 = 200
200/14 = 14.29
The answer is
14.29%
Answer:
Since both have equal length
9x - 2 = 6x + 13
9x - 6x = 13 + 2
3x = 15
x = 15/3
x = 5
Length of BC = 6(5) + 13 = 43 cm
