=> 20
Answer: 11
Step-by-step explanation: The sum of 15 and six times t will be 15 + 6t = 81.
Now, you subtract 15 from both sides to isolate the constants from the variables on the left side and on the other side and you will end up with 6t = 66. Then, you divide 6 from both sides to finally isolate the numbers from the variable and 66 divided by 6 would equal 11
Hope this Helps :)
1st one is 40
2nd is 4
3rd is 12
F(g(x))= -4(10x-6) + 7
f(g(x))= -40x + 24 +7
f(g(x))= -40x +31
