s - the number of the t-shirts;
h - the number of hats:
The system of equations:
s + h = 23
10 s + 12 h = 246
--------------------------
s = 23 - h
10 * ( 23 - h ) + 12 h = 246
230 - 10 h + 12 h = 246
2 h = 246 - 230
2 h = 16
h = 16 : 2
h= 8
s = 23 - 8
s = 15
Answer: The basketball team sold 15 t-shirts and 8 hats.

Answer: 4 7/20 gallons
Step-by-step explanation:
Gallons of soup made = 10 3/5
Gallons that was chicken noodle = 6 1/4
The gallons that wasn't chicken noodle will be:
= 10 3/5 - 6 1/4
= 10 12/20 - 6 5/20
= 4 7/20
Therefore, 4 7/20 gallons wasn't chicken noodle.

Answer:
A
Step-by-step explanation:
12x6=72
Answer:
A) y=-1/2x+55
Step-by-step explanation:
We can clearly see a negative trend/association between the number of hot drinks sold on a given day and the low temperature of that day. Therefore, the slope of the best line of fit must be negative, eliminating D and E. Also, notice that when the low temperature is 0°F, the number of hot drinks sold is about 55, which is a good indicator of our y-intercept or constant, eliminating choice C. Because the best line of fit is not so steep, the slope will be closer to 0 if it's a negative trend. This eliminates choice B, making the correct answer A.
