Answer:
M = (S -C)/C
Step-by-step explanation:
Starting with ...
S = C + MC
we want to solve for M.
S - C = MC . . . . subtract the term not containing M
(S -C)/C = M . . . . divide by the coefficient of M
Solved for M, the formula is ...
M = (S -C)/C
Let's say the number is 9. 10% of 9 is 0.9. Add that to 9 and you would get 9.9. 10% of 9.9 is 0.99. Subtract and you would get 8.91. Then you could do the rest.
Answer:
Step-by-step
The sum must be greater than 1 because
1/2 + 1/2= 2/2 or 1
ex
3/4 + 8/4= 11/4
9/16+15/16=24/16
8/8+9/8=17/8
Answer:
Step-by-step explanation:
So we would have to multiply the "2x - 8" by 5 each resulting in 10x - 40 + 15. Then we subtract which results in 10x - 25 = - 15. We add 25 to 25 and 15 resulting in 10x = 10. We divide each by 10 which results in x = 1.
