-9x + 1 = 80....subtract 1 from both sides
-9x + 1 - 1 = 80 - 1...simplify
-9x = 79...divide both sides by -9
x = -79/9 <== ur answer
The answer is B) Two times the sum of a number and two. That would be completely different that twice a number plus two.
Hope this helps!
Table:
x values: 5, 10, 15, 20, 25
y values: 7, 14, 21, 28, 35
First take the inside diameter and divide by 2 to get the radius (4cm)
Then use

r^2 with 'r' being your radius to get the area of the base
The area is 12.7 cm
Now multiply the height by the area of the base to get the volume/ capacity!
40cm x 12.7cm (rounded to the nearest tenth) = 502.7 cubic centimeters
