Answer:
and
Step-by-step explanation:
Assume that Mike bought only cookies and hot dogs.
The total can be represented as:
--- (1)
And the amount spent can be represented as:
--- (2)
Required
Determine the system of equation
Let c represents the number of cookies and h, number of hot dogs.
implies
And
Cost of cookies = 0.75 * c
Cost of hot dogs = 1.10 * h
So, we have:
Hence, the equations are:
and
Solving for c and h
Make c the subject in
Substitute 5 - h for c in
Collect Like Terms
Solve for h
-- approximated

Answer:
The slope is -2
Step-by-step explanation:
Since the roof is decreasing in height as it goes forward, I know that the slope must be negative. The equation to find the slope is rise/run. The vertical change, or the rise, is -6 feet, so that value goes on top of the fraction. The horizontal value, or the run, is 3 feet so that goes on the bottom of the fraction.
Now our fraction is 
If you simplify that fraction, you'll get -2.
