Answer:
m=-3
Step-by-step explanation:
3-2(9+2m)=m
3-2(9)-2(2m)=m
3-18-4m=m
-15-4m=m
-15=m+4m
5m=-15
Divide by 5
5m/5=-15/5
m=-15/5
m=-3
To check if correct, subsitute m for -3 in the equation. And both sides of the equation must be equal
3-2(9+2m)=m
3-2(9+2(-3))=-3
3-2(9-6)=-3
3-2(3)=-3
3-6=-3
-3=-3
Answer:
Step-by-step explanation:
7 + 8 = 15

You can make 11 batches of brownies. Divide 8.5 (8 1/2) by .75(3/4)
Answer:
This number can be found using the Rule of 70, which describes the formula dt = 70 / r, where dt is the doubling time, and r is the annual rate of growth.
Step-by-step explanation:
24/6 = 4
20 x 2 = 40 x 2 = 80 x 2 = 160 x 2 = 320
20 ---> 320 in the first day.
Keep doing this equation. Multiply each day's end result by 2 four times for 9 more days.
