Answer:
40 units
Step-by-step explanation:
On the number line, the distance between x and y is given by
|x-y|.
To find the distance between -70 and -30 on the number line, we find the absolute value of their difference.
Therefore the distance between -70 and -30 on the number line is 40 units.
Simplifying
5m + -7 = 6m + -9
Reorder the terms:
-7 + 5m = 6m + -9
Reorder the terms:
-7 + 5m = -9 + 6m
Solving
-7 + 5m = -9 + 6m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-6m' to each side of the equation.
-7 + 5m + -6m = -9 + 6m + -6m
Combine like terms: 5m + -6m = -1m
-7 + -1m = -9 + 6m + -6m
Combine like terms: 6m + -6m = 0
-7 + -1m = -9 + 0
-7 + -1m = -9
Add '7' to each side of the equation.
-7 + 7 + -1m = -9 + 7
Combine like terms: -7 + 7 = 0
0 + -1m = -9 + 7
-1m = -9 + 7
Combine like terms: -9 + 7 = -2
-1m = -2
Divide each side by '-1'.
m = 2
Simplifying
m = 2
Answer:
11x + 8 +8x +12 =27 (drop the parenthesis, there's no actual need for them)
19x +20 =27 (i combined like terms and then subtracted 20 from both sides)
19x = 7 (divide both sides by 19 to get x alone)
x= 7/19 or 0.36842105 (the answer)
