15-32= 32-15= 32 -15 15 -32
Answer:
Step-by-step explanation:
To solve this you take 0 as the starting number, he lost 20 points so you subtract 20 and get -20. Next add 15 points. You then get -5. Then he got another answer right so you add 35 to -5. It the same if you say 35-5. Which gives you 30. So your answer is 30
Answer to part A: If the sun produces 3.9 * (10^33) ergs or radiant energy for every second, then how much energy does the sun produce in 3.25 * (10^3) seconds? Just multiply (3.25 * [10^3]) * (3.9[10^33]) = <span>1.2675 * 10^37 of ergs of radiation.
Answer to part B: 1.435 * 10^3 mm is a reasonable answer because it is much smaller than </span>1.435 * 10^3.

Answer:
9 people should get on stop 1.
Step-by-step explanation:
If i understood it correctly .
13 people on bus initially.
at first stop - 4 people get off . So 9 people should be on bus.
But few get in bus ( that is what is asked in the question - but it is not super clear to me)
after 2nd stop - there are 12 people on bus.
at 2nd stop 6 people got off.. so there were total of 18 on the bus
So if there were 9 people on bus stop by stop 1 .. so 9 people should have got in bus at stop 1 to make it equal to 18.
Only doubt i have is : if the question is asking how many got on the 2nd stop. also i was not clear what does this line means - At the first stop, four people get off and to get on.
Answer:
I believe he can go on 30 rides.
Step-by-step explanation:
The equation would be 5 + .5x = 20
Because $5 to get in, plus $.50 per ride (x is number of rides you are solving for), and $20 is total amount you can spend.
So, .5x=15 so x=30
