Answer:
Easton entered in 25 shows last year.
Step-by-step explanation:
Given that Easton won best in show in 60% of the shows I have entered, to determine how many show was Easton entered if he won best in show 15 times last year, the following calculation must be performed:
60 = 15
100 = X
(100 x 15) / 60 = X
1,500 / 60 = X
25 = X
Therefore, Easton entered in 25 shows last year.
12x+12
Multiply 3 to everything in the parenthesis
so it becomes
18+12x-15
=12x+12
1/81
(1/3)⁴ = (1⁴/3⁴) = (1/81)
