The answer is that the coat costs $3.10 because you round $3.0975 to $3.10
Answer:So I calculate 8437−6526=1911. Then I multiply it by minus one to get 6526−8437, which is what I wanted.
Step-by-step explanation:
1) Vertical angles-the angles will equal each other.
8+7x=9x-4
12+7x=9x
12=2x
x=6
2) Supplementary-Angles will add up to 180
6+13x+7x+14=180
20+20x=180
20x=160
x=8
The slope should be 3/2, since you rise 3 and go over 2
