Sarah earns $9 an hour at a Mort's Pizza Palace, working 20 hours per week. She spends $3 each week for snacks at work, but saves all her other earnings.
How much does she save in a week?
A. $1
B. $9
C. $20
D. $177

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
