Answer:
m = 25/28
Step-by-step explanation:
It's best to enclose fractional coefficients inside parentheses to eliminate ambiquity: 2/7m-1/7=3/14 => (2/7(m - (1/7) = (3/14).
The LCD is 14; each of the denominators {7, 14} divides evenly into 14. Hence our equation becomes
(4)(m - 1/7) = 3
... after multiplying every term by 14.
Let's multiply each side by 7 to eliminate the remaining fraction:
4(7m - 1) = 21, or
28m - 4 = 21, or
28m = 25.
Hence, m = 25/28.
Answer:
80
Step-by-step explanation:
PEMDAS- do exponents first here, simplifying that to 64+16, add those to get 80.
Answer:
The answer is 5.9
Step-by-step explanation:
1) Subtract 31.7 from both sides.

2) Simplify 14 - 31.7 to -17.7

3) Divide both sides by -3.

4) Simplify -17.7/-3 to 5.9

5) Switch sides.

Therefor, the answer is x = 5.9.
-2 negative 2 is the answer
