A kid at the pool goes to the high diving board and climbs the stairs 3 feet and has to wait for the kid in front of him. He climbs up another 5 feet and then jumps into the pool descending 10 feet. How far does the kid need to swim up to reach the surface?

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

your correct answer is c. he organized a political resistance group based on islam.

im sorry for the poor quality answer.

first 15 divide by 2 = 7.5

100 divided by 7.5 is 13.

15 / 2 = 7.5

100 / 7.5 = 13.
