Sum of interior angles of polygon:
= 180(n - 2)
= 180(5-2)
= 180(3)
= 540

so
2x = 540 - (90+100+70)
2x = 540 - 260
2x = 280
x = 140

answer 
x = 140

Hope it helps

How many solutions does the equation 3x + 6 = −1 − 3 + 4x have? (5 points)
lianna [129]

Answer:

The equation has only one solution which is:

  • x = 10

Step-by-step explanation:

Given the equation

3x\:+\:6\:=\:-1\:-\:3\:+\:4x

Let us solve the equation to determine the type of the equation

3x\:+\:6\:=\:-1\:-\:3\:+\:4x

subtract the number: -1 - 3 = -4

3x+6=4x-4

subtract 6 from both sides

3x+6-6=4x-4-6

3x=4x-10

subtract 4x from both sides

3x-4x=4x-10-4x

-x=-10

Divide both sides y -1

\frac{-x}{-1}=\frac{-10}{-1}

x=10

Therefore, the equation has only one solution which is:

  • x = 10

A manufacturer of bicycles has determined that 550 bikes per month will be sold at a price of $250. At a price of $150, it is es
iogann1982 [59]

750 bikes would be sold for $350

Let x represent the number of bikes sold per month and y represent the price.

550 bikes are sold at a price of $250, this can be represented by (550, 250). Also, 750 bikes is sold at a price of $150, hence it is represented by (750, 150)

A linear function is represented by:

y = mx + b

m is the slope, b is the y intercept.

Therefore the function is:

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-250=\frac{150-250}{750-550}  (x-550)\\\\y=\frac{1}{2}x-25

The number of bikes sold for $350 is:

350 = (1/2)x - 25

x = 750

Therefore 750 bikes would be sold for $350
