Solve each equation a. 25-3x=40
b. 1/3(x-10)= -4
What does x equal to for each equation?

a. x = -5

b. x = -2

Step-by-step explanation:

a.

40=25-3x

40=25-(-15)

x should be -5 for a

b.

-4=1/3(x-10)

-4=1/3(-2-10)

-4=1/3(-12)

x should be -2 for b

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
