42 = 3x - 15 Since you know x = 19, you can plug in 19 for "x" in the equation
42 = 3(19) - 15
42 = 57 - 15
42 = 42 This is the solution
x = 19 is the solution because 3 • 19 – 15 = 57 – 15 = 42. (3rd choice)
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

Step-by-step explanation:
there is a right ∆ and a sector
area of right ∆ = .5×6×5 = 15 cm^2
area of sector = angle/360 * π * r^2
= 1/4 * π * 25 = 19.63 cm^2
area of the shape = 34.63 cm^2
