Ted can mow the lawn in 5 minutes by using his power mower. galen takes 15 minutes to mow the same lawn using a push-type mower. how many minutes would the job take if the two boys worked together?
if t is the time working together, which of the following expressions represents the portion of the job that ted will complete when the guys work together?

represents the portion of the job that Ted will complete when the guys work together.

Step-by-step explanation:

Let t be the time working together.

Given is : Ted can mow the lawn in 5 minutes by using his power mower. Galen takes 15 minutes to mow the same lawn using a push-type mower.

Working together, they are going to complete 1 job.

So, we can show this as:

=>

=>

=>

t = 3.75 minutes

So, while working together, they will take 3.75 minutes.

represents the portion of the job that Ted will complete when the guys work together.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
