Find the value of x,$3$3)/7:):7):7:

Step-by-step explanation:

We know that the sum of interior angles of a pentagon is:

=> (n-2) *180

Were n is the no. of sides

=> (5-2)*180

=> 3 * 180

=> 540

Hence, The sum of interior angles of a pentagon is 540.

So,

=> 3x - 5 + 6x + 25 + 5x - 10 + 5x - 10 + 6x + 25 = 540

Combining like terms

=> 3x + 6x + 6x + 5x + 5x - 5 + 25 + 25 - 10 - 10 = 540

=> 25x + 25 = 540

=> 25x = 540 - 25

=> 25x = 515

Divide both sides by 25

=> x = 515 / 25

=> x = 20.6

Hope this helped!

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
