Markesha because in the information in the text it appears that Eya runs 4 miles in 0.5 hours, that is, I want to get to the end that Markesha would beat Marta
because if you run 4 miles for 0.5 hours you would be reaching the finish line in less than 10 minutes

Answer:
(a) 15
Step-by-step explanation:
Each of the marked angles is an exterior angle of the polygon. The sum of exterior angles is always 360°. We can use that fact to write the equation.
4x° +77° +59° +6x° +74° = 360° . . . . . an equation to find x
10x + 210 = 360 . . . . . . . . . . . . . . divide by °, collect terms
x + 21 = 36 . . . . . . . . . . . . . . . divide by 10
x = 15 . . . . . . . . . . . . . . . subtract 21

<em>Comment on the sum of exterior angles</em>
Imagine the figure shrunk smaller and smaller until all of the angle vertices are the same point. You can see that those angles will completely fill the angular space around that central point, so they must have a sum of 360°.
Answer:
x = -7/2 multiplicity 2.
Step-by-step explanation:
4x^2 + 28x + 49 = 0
(2x + 7)(2x + 7) = 0
This is a perfect square.
2x + 7 = 0, so:
x = -7/2 multiplicity 2.
Answer: -12x^2 + 4x
Step-by-step explanation:
Samuel started out with 21 mowed lawns. 7(months) x 3(lawns) = 21
If he mows 3 lawns per month, then he would have to mow lawns for another 3 months. 3 x 3 = 9.
21 + 9 = 30
Although this is one mowed lawn over the objective, any less would not reach 29.
I'm not really sure what the question is asking, so here's two answers:
He would have to mow lawns for another 3 months in order to mow 29 lawns.
Or, he would have to mow 8 more lawns.
