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.

Answer:
12m - 4
☆ putting the value of m in the above formula
12 × 4 - 4
= 48 - 4
= 44
6r - 4
☆ Putting the value of r in the above formula
6 × 6 - 4
= 36 - 4
= 32

Answer:
Step-by-step explanation:
first you need to put the equation in y=mx+b form
y-3=(-1/2)(x+4)
y-3= (-1/2x)+4
y=-1/2x+1
then you just graph
the y intercept is 1 and the slope is -1/2 so it’s going to be a negative graph and it starts from 1 on the y axis
