You just divide 6/10 by 2/2 and that's 3/5.
Answer:
The answer is 91
Step-by-step explanation:
We have the following equality:

Then a must satisfy that
. So,
or
.
1) If a=7, then, it follows for the first equality that 56=14b. Then b=4. Finally, substituting b=4 in the first equality we obtain that -64=16-c. So, c= 80. We conclude that
.
As the problem states, we only consider values of a greater than zero. Then 91 is the only solution for
.

Answer:
2 tee shirts
5 sleeves
Step-by-step explanation:
Let the number of shortsleeves be S and longsleeves L.
Total is 7
That is
L + S = 7
Total money spent is $73, while shorts cost 9 and longs 11
Hence,
9S + 11L = 73
We now have two equations we can solve simultaneously. From the first equation,
L = 7 - S
Putting this in equation 2
9s + 11(7 - S) = 73
9s + 77 - 11S = 73
2S = 4
S = 2
Since s = 2, then L = 5
