$16.38 - $7 = 9.38 7 cents x 134 = 9.38 so the answer would be 134 minutes or 2h 14 min
Answer:
A
Step-by-step explanation:
To find a perpendicular line you first need to see the equation in slope intercept form. To do that you need to solve for y.
2x - 5y = 20 ---> subtract 2x from both sides
-5y = -2x + 20 ---> divide by -5
y = 2/5x - 4
Now that you have this, note that a perpendicular line has opposite and reciprocal slope. Since the slope in our equation is 2/5, that means the new line will have -5/2 slope. So we use the point given and the slope to find the y intercept.
y = mx + b
-8 = -5/2(7) + b ---> multiply
-8 = -35/2 + b ---> add 35/2 to both sides
19/2 = b
Now use our new slope and new y intercept to write the new equation.
y = -5/2x + 19/2

We know that:
Antrim's Population = 4 × Concord's Population
Antrim's Population = 2 × Bennington's Population
Antrim's Population + Concord's Population + Bennington's Population = 140,000
Let Antrim's Population be x, Bennington's be y, and Concord's be z. Substituting the values in the above equations, we get:
x + y + z = 140,000
We know x = 4 × z and x = 2 × y
Substituting values of y and z in terms of x
x + 
+ 
= 140,000
⇒ 
× x = 140,000
⇒ x = 80,000
and y = 80,000 ÷ 2 = 40,000 and z = 80,000 ÷ 4 = 20,000
Hence, Benington's population is y = 40,000
