3(x - 5) + 2 (3x + 1) = 45 solve for x

6.444 or 6&4/9

Step-by-step explanation:

3(x-5)+2(3x+1)=45<distributive property

3x-15+6x+2=45    <combine like terms

9x-13=45              <addition property of equality

9x=58                   <division property of equality

x=6.444...

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.
