Answer: A) x = 2

Step-by-Step Explanation:

9(x + 1) = 25 + x
9 * x + 9 * 1 = 25 + x
9x + 9 = 25 + x (Shift +x to LHS)
9x - x + 9 = 25 (Shift +9 to RHS)
9x - x = 25 - 9
8x = 25 - 9
8x = 16 (Shift *8 to RHS)
x = 16/8
=> x = 2

Therefore, x = 2

It took Brian 6 hours to drive to the sales conference. He took the same route on the way back home, but

g100num [7]

Answer: 54 mph

Step-by-step explanation:

d-the distance

s+9 - the speed to the conference

d=6*(s+9)

s- is the speed on the way back home

d=7*s

so 6*(s+9)=7*s

6s+54=7s

-6s -6s

54= 7s-6s

s=54 mph
