First divide 40 by 8 to get the variable m by itself then you’ll get 5 so 5 is the answer for 4 and for 5 x= 1 since 6/6 is 1 and for 6 you just have to reverse it just like you did for question 5 so now it’s 9• 8= t so t equals 72 and this can be checked by doing 72/8= and that equals 9:)
C = 25 + 7h...c = 81
81 = 25 + 7h
81 - 25 = 7h
56 = 7h
56/7 = h
8 = h......so at 8 hrs, it will cost $ 81
X^2 +6x -5 = 0
x^2 +6x = 5 . . . . . add 5
x^2 +6x +9 = 14 . . . add 9
(x +3)^2 = 14 . . . . . . write left side as square
x +3 = ±√14 . . . . . . . take the square root
x = -3 ±√14 . . . . . . . subtract 3
Selection C is appropriate.
