Answer:
28 short race volunteers
76 long race volunteers
Step-by-step explanation:
Let :
Short races = a
Long races = b
LAST YEAR:
7a + 8b = 804 - - - - (1)
THIS YEAR:
11a + 5b = 688 - - - (2)
Multiply (1) by 5 and (2) by 8
35a + 40b = 4020
88a + 40b = 5504
Subtract
-53a = - 1484
a = 1484 / 53
a = 28
Put a = 28 in equation (1)
7(28) + 8b = 804
196 + 8b = 804
8b = 804 - 196
8b = 608
b = 76

76 long race volunteers

Answer:
y =-1/4x -8
Step-by-step explanation:
3x+12y=-96
Slope intercept form is y = mx +b where m is the slope and b is the y intercept
Subtract 3x from each side
3x -3x+12y=-3x-96
12y = -3x-96
Divide each side by 12
12y/12 = -3x/12 -96/12
y =-1/4x -8
