What is the solution of this question?
3x+17+5x=7x+10

x=-7

Step-by-step explanation:

3x+17+5x=7x+10

Step 1: Simplify both sides of the equation.

3x+17+5x=7x+10

(3x+5x)+(17)=7x+10(Combine Like Terms)

8x+17=7x+10

8x+17=7x+10

Step 2: Subtract 7x from both sides.

8x+17−7x=7x+10−7x

x+17=10

Step 3: Subtract 17 from both sides.

x+17−17=10−17

x=−7

x=−7

you can't solve x because it is 2 linear equation and you only have one equation

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.
