A soccer team ordered 12 jerseys and 12 pairs of shorts, for a total of $156. Later, they had to order 4 more jerseys and 6 more
lyudmila [28]

Answer:

Jersey cost $8 and pair of shorts $5

Step-by-step explanation:

There are several ways to solve this, but I will find the solution using the system of equations.

Let's mark price of jersey with x, and price of pair of shorts with y. That means:

12x + 12y = 156

4x + 6y = 62

Now, we can multiply the second equation with -2 to cancel out y:

12x + 12y = 156

-8x - 12y = -124

That only leaves us with:

12x - 8x = 156 - 124

4x = 32

x = $8

Now we plug the value for x into any equation to find y:

4x + 6y = 62

32 + 6y = 62

6y = 30

y = $5

chegg tell whether each sequence is arithmetic. if the sequence os arithmetic, identify the common difference and find the indic
spin [16.1K]

No, the given sequence is not an arithmetic sequence.

What is Arithmetic Sequence ?

An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.

In the above question,

The sequence is 3,5/2,3/2,-3/2,...

Take the 2nd term and minus the 1st term.

Now take the 3rd term and minus the 2nd term.

We can clearly notice that the differences are not same. Hence there is no common difference and therefore it's not an arithmetic sequence
