Answer:
The number of wrapping paper sold was 32 and the number of magazines sold was 40
Step-by-step explanation:
Let
x ----> the number of wrapping paper sold
y ----> the number of magazines sold
we know that
The classes sold 72 items
so
----> equation A
The classes earned $222 for their school
so
----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is (32,40)
see the attached figure
therefore
The number of wrapping paper sold was 32 and the number of magazines sold was 40
B
volume= length x width x height
Divide 235/5 so 47 check by doing 47 times 5 it checks so the answer is 47
"x" is the "alternate interior" to the missing angle atop, and a flat-line, is just a line with an angle of 180°, thus, 28 + 103 + x = 180
