Answer:
Step-by-step explanation:
3x + 2y = 6
2y = -3x + 6
y = -3/2x + 3.....slope here is -3/2 and y int is 3
-4x + 6y = 15
6y = 4x + 15
y = 2/3x + 5/2.....slope here is 2/3 and y int is 5/2
different slopes, different y int means exactly ONE SOLUTION
373-13=360
360 divided by three equal to 120
So 120 children chose basketball
7 1/2 is 7.5 and 3/4 is .75, so 7.5 divided by .75 is 10.
-2,-1,3,7
HAVE A GREAT DAY!!
