15 - 9a - 3b + 5 - 6b
15 - 9a - 9b + 5
20 - 9a - 9b
Step-by-step explanation:
15-3(3a+b)+5-6b
Multiple everything inside of the parenthesis by -3.
15 - 9a - 3b + 5 - 6b
Get the variables together by doing -3b-6b
15 - 9a - 9b + 5

Answer:
T is equal to I divided by pr.
Step-by-step explanation:
This is the equation for interest.
I is interest.
P is the principal
r is the interest rate
t is the time in years
you have to isolate for t.
Because multiply p times r times t, divide both sides by pr due to the fact that division is the inverse operation of multiplication
Then you are left with t= i divided by pr.
