Answer:
x1= -7 , x2= 1
Step-by-step explanation:
The problem statement suggests you should convert dimensions to inches to work this problem.
.. 2.75 ft = 33 in
.. 1.5 ft = 18 in
The empty height is
.. 0.6*7 in = 4.2 in
so the empty volume is
.. V = (33 in)*(18 in)*(4.2 in) = 2494.8 in³
Multiplying this by the conversion factor to gallons gives
.. V = (2494.8 in)³ × (1 gal)/(231 in³) = 10.8 gal
It will take 10.8 gallons of gas to fill the tank.
500g = $0.95
100g = $0.95 ÷ 5 = $0.19
800g = $0.19 x 8 = $1.52

Answer: 800g will cost $1.52

Answer:
3.17
Step-by-step explanation:
2.5/1.5 = 1.66667, 1.66667 (it goes on infinitely 1.6666 etc.)
1.66667 x 1.9 = 3.166666654, and when rounded to nearest tenth it is 3.17
