Molly and Lynn both set aside money weekly for their savings. Molly already has $650 set aside and adds $35 each week. Lynn already has $825 set aside but adds only $15 each week. Which inequality could they use to determine how many weeks, w, it will take for Molly's savings to exceed Lynn's savings?

A. 650 + 35w > 825 + 15w

Step-by-step explanation:

Molly = $650

Molly's weekly additions = $35

Lynn=$825

Lynn's weekly additions= $15

Let the number of weeks = w

inequality to determine how many weeks, w, it will take for Molly's savings to exceed Lynn's savings

Molly's savings

$650+ $35w

Lynn's savings

$825 + 15w

The inequality is

650 + 35w > 825 + 15w

The inequality above will show the number of weeks it will take for Molly's savings to be greater than Lynn's savings

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.
