2(p+w)=240
p+w=120
w=120-p, we will use this value for w below...
2(p-w)=210
p-w=105, now use the w from earlier...
p-120+p=105
2p-120=105
2p=225
p=112.5 mph (and wind is 7.5 mph)
First you find your slope which is rise/run, so, 1/3, and a line this way (/) is positive, so it's positive 1/3.
Then you see where it crosses the y axis: -1.
Plug that into y=mx+b giving you y=1/3x-1.
Your answer is D.
Answer:
2
Step-by-step explanation:
22 - 2y
= 22 - 2 ( 10 )
= 22 - 20
= 2
Answer:
Choice (3) 
is correct.
Step-by-step explanation:
Given expression is 
Now we need to simplify this and check which of the given choices best match with it.
