Answer:
a. False
b. True
c. True
d. I think it's true
e. False
Step-by-step explanation:
a. The unit rate is 19.75 gallons per minute
b. It is true because when x=0 y is also equal to 0, therefore it passes through the origin
c. 19.75 is about 20, and 20 multiplied by 5 is 100
d. Like I said before I don't know but I hope you get it correct ._.
e. When x=8 the equation would be 19.75*8 which is equal to 158 not 150

Answer: 131 degrees</h3>
Work Shown:
(angle JIW) + (angle WIH) = angle JIH
(2x+8) + (101) = 11x + 10
2x+109 = 11x+10
2x-11x = 10-109
-9x = -99
x = -99/(-9)
x = 11
So,
- angle JIW = 2x+8 = 2*11+8 = 22+8 = 30 degrees
- angle WIH = 101 degrees
- angle JIH = 11x+10 = 11*11+10 = 121+10 = 131 degrees
The smaller angles add to 30+101 = 131 to confirm we have the correct answer.
