For this problem you have to isolate the variable. To do this you must inverse the operations. Multiply 18 by 5, then divide by 12 to get your answer of 7.5
Price increase is $ 22-20 =$2 so the percent increase is 2/20 x 100= 10%
Answer:
6.8
Step-by-step explanation:
a^2 + b^2 = c^2
6.6^2 + b^2 = 9.5^2
43.56 + b^2 = 90.25
b^2 = 90.25 - 43.56
b^2 = 46.69
(take square root of both sides)
b = 6.8
100,000 + 2,000 + 400 + 50 + 3
the answer is 1
