77% because if you add 20% to 3% you get 23% total and 100%-23%=77%.
Answer:
15x + 30
Step-by-step explanation:
Let x represent the number of weeks someone is a member. 30 is constant because it never changes.
Find the greatest common factor which is 9
9(9x^2-3x-2) and then factor the equation in the parenthesis
so the factored equation will be 9(3x+1)(3x-2)
49 = -7 (t + 1)
49 = -7t + 7
-7 -7
42 = -7t
÷ -7 ÷ -7
-6 = t
t = -7
