Answer:
Step-by-step explanation:
10 3/9 - 10 2/5
we need to convert mixed fractions to improper fractions
Now, we have 93/9 - 52/5
We need to equate the denominators, before subtracting them.
The result of 10 3/9- 10 2/5 is - 3/45

1. Answer:
C. 1050
Step-by-step explanation:
To find the area of a rectangle, it is length * width * height

The radius of the cylinder is 20
The height of the cylinder 25
πr2h is the formula used to find the volume of a cylinder
Answer:

Let the number of students in the class be x
Let the number of pieces of gum she gave out be 3x
Equation
3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.
3(x - 1) + 8 = 168 This doesn't work either.
Well we have to choose. It's a rounding problem.
3x + 8 = 168 Subtract 8 from both sides.
3x = 168 - 8 Combine
3x = 160 Divide by 3 on both sides.
x = 160 / 3
x = 53.333333333
Since that can't be, we could say there were 53 students.
