This is easy. You all need to do this:
100÷2 it equals 50.
You need to subtract one 50 from either Caroline/Mohamed(Take Caroline's for example)
Caroline = 50-16=34.
Then you add 16 to 50(Mohamed's)
50+16=66
Therefore, Caroline sold 34 tickets, however, Mohamed sold 66 tickets.
To prove: add 66+34
66+34=100

Mohamed sold 58, and Caroline sold 42.

We need to follow PEMDAS.

We need to do the multiplication before we can do the addition (which becomes subtraction because of the sign).

3 + 2 • (–8)

3 + (-16)

3 - 16

The width of a rectangle is 6 ft. What os the perimeter of the rectangle if its area is 42 square feet? A 26 feet B 36 feet C 42 feet D 48 feet

Answers

Area (rectangle)=lenght x width
width= 6 ft
area=42 ft²

1) we have to calculate the length.
42 ft²=lenght x 6 ft
length=42 ft²/6 ft=7 ft

2) Now we have to calculate the perimeter.
Perimeter=2 lenght + 2 width
Perimeter=2(7 ft) + 2(6 ft)=14 ft + 12 ft=26 ft

answer: the perimeter is 26 ft.
