Convert 30 m/s to miles per hour.
Use 1 mile per hour = 1.61 km/h

1 = 1.61

30 = x

1.61 x 30 =

48.3

67.08 m/h

Step-by-step explanation:

need to convert 30 m/s to km/h = 108 km/h

1 = 1,61

x=108

x=108/1.61

30 m/s = 67.08 m/h

the y will be in still but your answer will be y x 3

step-by-step explanation:

jk: )

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
