Can someone solve for x??
miskamm [114]

Sum of interior angle of polygon: S = (n-2) * 180°,

where n is number of sides and where S is total degrees.

With 6 sides, n = (6-2)*180 = 720°

Then set all of the interior equations equal to the sum, or

720 = 5x + 4x+2 + 5x+6 + 2x-2 + 3x+5 + x-10

720 = 20x + 1

719 = 20x

x = \frac{719}{20} = 35.95

The function C=120+.20m represents the cost see in dollars of renting a car after driving miles how many miles would a customer
faust18 [17]

Customer have to drive 100 miles for cost to be equal to $140

<u>Solution:</u>

Given function is as follows

C = 120 + 0.20m  

Where "C" represents cost in dollar of renting a car and "m" represents number of miles.

If we see the given equation, we can say that fixed cost is 120 and variable cost is 0.20m which is dependent on number of miles car is driven.

We need to calculate number of miles so that total cost that is C = $140

On substituting C = $140 in given function, we get

140 = 120 + 0.20m

On Solving above equation for m we get

140 – 120 = 0.20m

=> 20 = 0.20m

=> m = \frac{20}{0.20} = 100 miles

Hence customer have to drive 100 miles for  cost to be equal to $140.
