Answer:
There were 261 Cheeseburgers and 87 Hamburgers sold on Tuesday
Step-by-step explanation:
Lets write some equations where H=Hamburgers and C=Cheeseburgers:
1) H+C=348
2) C=3H
1) Substitute 3H as C in the first equation:
3H+H=348
2) Combine alike terms:
4H=348
3) Divide both sides by 4:
H=87
4) Now, substitute 87 as H in the first equation:
87+C=348
5) Subtract 87 from both sides:
C=261
Use the Pythagorean theorem:

Please consider the complete question.
A parking lot in the shape of a trapezoid has an area of 12,052.1 square meters. The length of one base is 82.4 meters and the length of the base is 108.6 meters. What is the width of the parking lot
We will use area of trapezoid to formula to solve our given problem.
, where
a and b represents parallel sides of trapezoid,
h = height of trapezoid.
Width of the trapezoid will be equal to height.
Upon substituting our given values in above formula, we will get:





Therefore, the width of the parking lot is 126.2 meters.
You have to combine -5.8c+1.4c which = -4.4c
then
combine 4.2-3.1 which = 1.1
so the answer is
-4.4c+1.1 or you can switch the numbers around
