Answer:
18
Step-by-step explanation:
It means that two people are friends, like two peas in a pod
QRS = DRS + QRD
167 = x + 143 + x + 30
167 = 2x + 173
-2x = 173 - 167
-2x = 6
x = 6/-2
x = -3
DRS = x + 143
= (-3) + 143
= 140
I would say the answer is E. The coach cannot select those he observes. the reason being is because all people can run a different time due to the age of the person, not saying that they have a limit but the question leaves out how fit the player is. to put in words a athletic person on the average could run about 4-5 laps depending on how far each lap is. Hope that helps
