The amount of gas in her tank after 8 days given the linear equation g = 213 - 1.6d is 200.2 gallons of gas
<h3>Linear equation</h3><h3 />
- Gallons of gas used per day = 1.6 gallons
- Number of days = d
- Quantity of gas = g
The equation
g = 213 - 1.6d
Gas remaining after 8 days
g = 213 - 1.6(8)
= 213 - 12.8
g = 200.2 gallons of gas

Answer:
±90
Step-by-step explanation:
√(-225) · √(-36) = (15i)·(6i) = 90i² = 90·(-1) = -90
_____
On the other hand, ...
... √(-225) · √(-36) = √((-225)·(-36)) = √8100 = 90
___
If you consider all the roots at each stage, the result is ±90. Since you're working with complex numbers here, it is reasonable to recognize every number has two square roots.
... √(-225) = ±15i
... √(-36) = ±6i
... √(-225) · √(-36) = (±15i)·(±6i) = ±90i² = ±90
Answer:
The Jason's company charges more than the contractor's company.
Step-by-step explanation:
There are two expressions given for total charges for two companies as 81 x+108 and 103 x+64.
Here x represents number of hours.
We are asked to find difference in total charges if that takes 45 minutes.
45 minutes = 
hours.
Plug in this value for x.
81x+108 =
Simplify it
60.75 +108 =168.75
Now, for 103x+64 =
Simplify it,
77.25+64=141.25
If we see the total charge for both companies for 45 minutes, the Jason's business computers charges more than contractor's company.
