Answer:

2x-10+x+x+10=180, or 4x=180

Step-by-step explanation:

So since the total is 180, you add them all up like an equation.

So,

2x-10+x+x+10

Combine like terms

4x=180

x=45

Then plug it back in to the equations.

x=45

(2x-10)=80

(x+10)=55

shtirl [24]

Question:

Charlotte has been working for her company for x years. Travis has been working for the same company exactly 3 years longer than Charlotte. What is the range of the relationship?

A- y>0

B- y>3

C. y<3

D. 0

Answer:

y > 3

Step-by-step explanation:

Number of years Charlotte has worked = x

Number of years Travis has worked = y. ie, y = 3+x

Let's assume the function reaches its lowest point at 3. There could also be a higher value for this function.

We now have:

f(x) = y > 3

Since Travis has been working for the same company exactly 3 years longer than Charlotte the range of the relationship is y>3
