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
