If the original angle is x degrees then its supplement is 180 - x degrees.
we have the equation:-
180 - x = 3x + 20
160 = 4x
x = 40
The original angle is 40 degrees and its supplement is 140 degrees
A. Judy made a mistake between Steps 1 and 2
To factor
, you have to factor it as
, not
, because that will leave an extra 6x because of 8x - 2x.

Answer:
0.125
0.125x = Distance Traveled in Miles
0.125 * 11 = 1.375 Miles Ran
Step-by-step explanation:
First divide 1 mile by 8 minutes
1 mi / 8 min = 0.125 mi
Then you simply show 0.125 * x (x being the number you insert to find the distance) = How far you ran
0.125x = Distance Traveled in Miles
Finally you insert 11 for x and multiply to find the distance
0.125 * 11 = 1.375 Miles Ran
Answer:
x = 6
Step-by-step explanation:
8x = 48,
Divide each side by 8 to isolate x
8x/8 = 48/8
x = 6
