Abarrel of oil was being folled at a constant rate of 7.5 gal/min. the barrel had 10 gallons before filling began

Thank you for posting your question here at . I think your question is incomplete. I will assume that you are looking for the equation of the above situation. I can only form an equation from this: y = 7.5x + 10. I hope the answer will help. 

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

The operation is suck a c@ck? !
