Answer: x = 14

Step-by-step explanation: you can solve this two different ways. By using corresponding angles or vertical angles. Either way, the angles will sum to 180 either by linear pairs or by same side interior angles.

(5x-14) + (8x+12) = 180. Combine like terms.

13x-2 = 180. Add 2 to both sides. 13x = 182. Divide both sides by 13. X = 14.

Each time Kristine gets paid, she spends $20 and saves the rest. If the amount Kristine earns is represented by x and the amount

faust18 [17]

We are given that Kristine spends $20 and saves the rest each time she get paid.

We can use slope-intercept form y=mx+b to represent the equation.

Where x represents the amount Kristine earns and y represents the amount she saves.

Kristine spends $20. Therefore b= -20.

Plugging mx as just x and b=-20.

<h3>y = x-20.</h3><h3>If we plug y=0, we get </h3><h3>0 = x-20</h3><h3>x=20.</h3><h3>We can see in 4th option we have x-intercept =20.</h3><h3>Therefore, correct option is 4th option. </h3><h3 />
