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
Ratio for this mean for every 10 cats sold there was one dog
60/10 = ?
6 dogs
ratio = 60:6
The Answer would be C, because if you divide 3/4 by 2/3 you have to switch numerators and denominator for 2/4, once you multiply that you get 9/8 you change that to a mixed number. Then you get C
It's linear
If you evaluate x when it's 0 you'll get the cut in y, that means the function will pass on (0,7)
The formula for linear functions is y=mx +b
In this case b is 7
M=7-5/0+1
M=2
Now you just write the function down, it would be
F(x) =2x + 7
