The swimming pool in an exclusive subdivision has 4 inlet pipes and one outlet pipe. The pool always has 250 cubic meters of
water in the bottom. If every inlet pipe brings in 25 cubic meters
of water per hour, and the outlet pipe drains 10 cubic meters per
hour, the relationship between the volume of water in cubic meters
V and the time in hours + when all the pipes are open is given by
V(1) = (4×25-10)t + 250 = 90% + 250 where + > 0. How much
time is needed for the pool to have 655 cubic meters of water?

Solution to the question is in the photo

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
