Ronald is making hats and scarves for charity. he has enough yarn to make 5 hats and 8 scarves. it takes him 12 hours to knit a hat and 6 hours to knit a scarf; he has 20 hours to knit. let x represent the number of hats made. let y represent the number of scarves made. which inequalities are among the constraints for this situation? select each correct answer. y≤8y≤8 5x+8y≤205x+8y≤20 12x+6y≤2012x+6y≤20 x+y≤20x+y≤20 x≤5

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

answer: its the third option.
