The phrase “six less than twice y” can be represented by the algebraic expression:
a. 2y - 6
b. 2y + 6
c. 6 < 2y
d. 6 > 2y

A

Step-by-step explanation:

we are given that

six less than twice y

so first twice of y can be written as 2y

then 6 less than this 2y can be written as 2y-6

A

45

step-by-step explanation:

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.
