three shirts and 2 pairs of jeans cost 95$. one shirt and one pair of jeans cost 40$. write a system of equations for the scenario.

3s+2j=95

s+j=40

Step-by-step explanation:

We need to create equations for both statements.

s=shirts j=jeans

(s & j can be replaced by any letter i just used s and j to avoid further confusion)

3s+2j=95

s+j=40

If you need me to solve it i can do that too but it seems you just need the equations

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.
