Two teams can be selected out of 10 teams in C(10,2) = 10!/8! 2! = 45 ways
=> If each team plays exactly 3 matches with each other team, number of matches will be 45 x 3 = 135.

Un cuaderno = $5
Un lapicero = $3
7 cuadernos × $5 = $35
3 lapiceros × $3 = $9
$35+$9=$44
7 lapiceros × $3 = $21
3 cuadernos × $5 = $15
$21+$15=$36
Answer:
- see the attached for the sums
- the magic number (sums of rows, columns, diagonals) is -6
Step-by-step explanation:
The directions tell you what to do and give an example. That work is to be repeated 15 more times. The work is tedious, at best. I found it slightly less tedious to enter the 64 numbers into a spreadsheet and let it do the sums. See the attached for the result.
At the bottom of the array are the sums of columns. At the right are the sums of rows. The upper right and lower left numbers are the sums of the corresponding diagonals.
The "pattern" is that the sums are all -6, which is what you expect from a magic square.
Answer:
B
Step-by-step explanation:
For this problem, let us find the respective speeds of Jasmine and Caroline and compare the two. All we have to do is divide #minutes by #miles to find the time spent per <u>one</u> mile.
Jasmine:

minutes per mile
Caroline:

minutes per mile
Since Caroline takes longer to run a mile than Jasmine, We now know that Jasmine ran at a faster pace:

<u>B. Jasmine ran at a faster pace because she ran 0.3 minutes faster per mile.</u>
