What is m if -2m plus 7 equals m-2?
-2m + 7 = m - 2 +7 +2 = m +2m 9 = 3m 3m = 9 m = 9/3 = 3 to test: -2(3) + 7 = (3) - 2 -6 + 7 = 3 - 2 1 = 1
Negative 1 over 2 m equals -9?
-1/2m = -9 To solve this: Multiply by 2m: -1 = -9*2m Divide by -9: -1/-9 = 2m Divide by 2: (-1/-9)/2 = m Work it out: -1/-9 = 0.111... (the 1 is recurring) 0.111... / 2 = 0.0555... (the five is recurring) So x = 0.055... or 5/90
What is m squared-2m-65 equals -2 using the quadratic equation?
m = 9 This is because, if: m squared - 2m - 65 = 2 Then: m squared - 2m = 65 + -2 m squared - 2m = 63 So: 63 = m squared - 2m m squared - 2m = m x m - 2m This means: 63 = m (m - 2) So something times itself minus two is 63. Going through different numbers, it is clear that 9 and 7 work. So: m x (m - 2) = 9 x (9-2) = 9 x (7) = 9 x 7 = 63 M is therefore 9.
What is m if 2m-9 equals 12?
2m - 9 = 12→ 2m - 9 + 9 = 12 + 9→ 2m = 21→ 2m ÷ 2 = 21 ÷ 2→ m = 101/2 = 10.52m - 9 = 12Add 9 to each side of the equation:2m = 21Divide each side by 2 :m = 10.5
What is the answer to the equation -2m 16m-9?
m=1/2 -2m=16m-9 -18m=-9 m=1/2
How do you solve -7(1-4m)13(2m-3)?
We can't solve anything without an equals sign, but let's assume the problem is -7(1 - 4m) = 13(2m - 3) Do the multiplication. -7 + 28m = 26m - 39 -7 + 2m = -39 2m = -32 m = -16 Check it. -7 x 65 = 13 x - 35 -455 = -455 It checks.

What is 12m plus 9-2m-16?
10m - 7
How do you solve 2m plus 717?
2m + 717 is an expression. It has no equality (or inequality) sign and so there is nothing to solve.
What is m squared-2m-65 equals -2 using the quadratic equation?
m = 9 This is because, if: m squared - 2m - 65 = 2 Then: m squared - 2m = 65 + -2 m squared - 2m = 63 So: 63 = m squared - 2m m squared - 2m = m x m - 2m This means: 63 = m (m - 2) So something times itself minus two is 63. Going through different numbers, it is clear that 9 and 7 work. So: m x (m - 2) = 9 x (9-2) = 9 x (7) = 9 x 7 = 63 M is therefore 9.
What is m if 2m-9 equals 12?
2m - 9 = 12→ 2m - 9 + 9 = 12 + 9→ 2m = 21→ 2m ÷ 2 = 21 ÷ 2→ m = 101/2 = 10.52m - 9 = 12Add 9 to each side of the equation:2m = 21Divide each side by 2 :m = 10.5

6m plus 7 - 2m plus 1?
6m + 7 - 2m + 1 = 4m + 8 If you meant: (6m + 7) - (2m + 1) = 4m + 6
What is the expression of 2m+9?
9
How do you solve 9 plus a equals 7?
You start by writing it down, then you solve by adding or subtracting equal amounts from both sides, until you get the A by itself. 9 + A = 7 9 + A (- 9) = 7 (- 9) <subtract 9 from both sides> A = 7 - 9 <on the left side, 9-9=0, so they cancel each other out> solve or simply the right side for the final answer
