Answer:
add 2x to both sides
Step-by-step explanation:
-x+2y=-10
2y=x-10
y=1/2x-5
0.56
3712-2914= 798 pounds
b. 40
The value of x (exterior angle) is equal to half of the difference of given arcs
(100 - 20) ÷ 2 = 40
sqrt(200) ≈ 14.14213562373095
14 = 14
14/3 ≈ 4.666666666666667
From least-to-greatest:
14/3, 14, sqrt(200)
