Kevin deposited $250 each month for the first 3 months in his savings account. then, he deposited $302.50 each month for the next 4 months. what is the average amount that kevin deposited each month?

he averaged about $280 a month in deposits

(3($250+4(302.50))/3months+4

=(750+120)/7

=1960/7=280

280 per month

55? i think maybe

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
