Answer:
x = 44
Step-by-step explanation:
So far, so good.
Now add the opposite of 0.8 to both sides.
0.2x = 8.8
And multiply both sides by 5 (equivalently, divide by 0.2).
x = 44
The linear function that can be used to determine the height, H, of the plane after m minutes is given by:
H(m) = 8000 - 500m
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value.
In this problem:
- The plane is descending from an altitude of 8,000 feet, hence the y-intercept is b = 8000.
- The plane descends at a constant rate of 500 feet per minute, hence the slope is of m = -500.
Thus, the equation is:
H(m) = 8000 - 500m.

2.385 can be written as 2385/1000, which is equivalent to 477/200. As a mixed number it is writte as 2 77/200. Hope I helped!
