There are 9 boxes of crayons with 8 crayons in each
box. Which of these would you use to figure out the
total number of crayons?

A 72 = 8 = 0
C 8 +9= 0
B 8 X 9 = 0
D72 -0 = 9

Renee chose A as the correct answer. Explain why
that answer isn't correct.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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.
