Answer:
9 white ribbons were awarded
Step-by-step explanation:
make white x
make blue b and make red r
b=x-1
r=x+3
w=x
add them up
x-1+x+3+x=29
x-1 +x+3 is 2x+2
2x+2+x=29
3x+2=29
subtract 2 on both sides
3x=27
divide by 2
x=9
2/4 and 1/2
5/10 and 1/2
1/3 and 2/6
40/90 and 4/9
125/5= 25
25 feet per second
3 ft, 3 ft, 2 ft
This will form a triangle
