((1/3)x - 5) + 171 = x
combine like terms...move the x’s to one side...
166 = (2/3)x
get x by itself...
166 (3/2) = x
249 = x
Answer:
63.1 pounds
Step-by-step explanation:
1. Change the percentage into a decimal.
12.5% ↔ .125
2. multiply the percentage as a decimal with 72.
72x.125= 9 (this is the same as what is 12.5% of 72)
3. Subtract the number you just got from 72
72-9= 63
Answer:
The exterior angles need to equal 360 degrees.
You have 70 + 65 + 75 = 210
So 2x + 3x need to equal 360 - 210 = 150
5x = 150
x = 150 /5 = 30
2x = 2 *30 = 60
3x = x *30 = 90
An interior angle and an exterior angle need to equal 180 degrees.
The largest interior angle would need to correspond with the smallest exterior angle.
The smallest exterior angle is 2x which equals 60 degrees.
The largest interior angle would be 180 - 60 = 120 degrees.
