step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

they charge the same amount at 20 minutes.

step-by-step explanation:

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:

he answer is x=1x3 because x=1 to x=3
