Do 5 times 2 and 3/5 so the answer would be 10 3/5
Step-by-step explanation:
x - 1 + 5x = 23
6x - 1 = 23
6x = 23 + 1 = 24
6x = 24
x = 24/6
x = 4 ans.

Answer:
x = 48
Step-by-step explanation:
We now that supplementary angles (as is the case for a straight line) add up to 180 degrees.
3x - 12 + x = 180
4x = 192
x = 48
Amount of increase = 20-12 = 8
Percentage increase = 8/12 = 0.666... 66.666...% ≈ 67%
