Dunno. wish there were more points than this though. bye
if his wasn't algebra, I would've answered answered. hope you have your answer by now though.
Information given:
- <u>100 passengers in each train car</u>
- <u>10 train cars total</u>
- <u>30 trains total</u>
<em>So we are trying to find the total number of passengers on all 30 trains?</em>
<u />
Step-by-step:
100 x 10 = <u>1,000 passengers per train</u>
1,000 x 30 = <u>30,000 passengers total within the 30 trains</u>
Answer: <u>30,000 passengers</u>

Given:
It is given that,
PQ ⊥ PS and
∠QPR = 7x-9
∠RPS = 4x+22
To find the value of ∠QPR.
Formula
As per the given problem PR lies between PQ and PS,
So,
∠QPR+∠RPS = 90°
Now,
Putting the values of ∠RPS and ∠QPR we get,
or, 
or, 
or, 
or, 
Substituting the value of in ∠QPR we get,
∠QPR = 
or, ∠QPR = 
Hence,
The value of ∠QPR is 40°.
