The first term of an arithmetic sequence whose common difference is 7 and whose 22nd term is given by A2 = 143 is which of the following?

The second term of an arithmetic sequence is 4. The fifth is 10. Find the first term. In this task we have 2 terms given: a2 = 4 and a5 = 10. We can use the n −th term formula to build a system of equations:

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.

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.
