If i have a 100 gallon water tank and use 5 gallons per minute while feeding it 2.5 gallons per minute will that tank run out of water

Find the value of ax 4 ; a = 2, x = 1. select one: a. 2 b. 4 c. 1 d. 8

The sum of the first eight terms of an arithmetic progression is 9m + 14. the fifth term of the06 progression is 2m - 6, where m is a constant.given that the first term of the progression is 26,find the value of the common difference, d and thevalue of m.

Me d is also an option but i couldn't get it in the picture
