Answer:
Jeff's ribbon is,
feet long
Step-by-step explanation:
Let J represents the length of Jeff ribbon and B represents the length of Bill ribbon.
As per the condition:
Jeff's ribbon is 3/7 the length of Bill's ribbon.
⇒
......[1]
It is also given that: if both ribbons combined are 2 feet long.
⇒J + B = 2 ......[2]
Substitute the equation [1] into [2] we get;
![\frac{3}{7}B+B = 2](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B7%7DB%2BB%20%3D%202)
Simplify:
![\frac{10}{7}B = 2](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B7%7DB%20%3D%202)
Multiply both sides by
we get;
ribbons
Substitute the value of B in equation [1] we have;
feet
Therefore, Jeff's ribbon is,
feet long

Answer:
1/6
Step-by-step explanation:
The probability of getting 2 the same colour here is 1 out of 6. Very low chance.
You need to show the data above
Distribute ^3 to both 6 and k^3
6^3 = 6 x 6 x 6 = 216
(k^3)^3 = k^9 (because you are multiplying k^3 x k^3 x k^3)
216k^9, or C) is your answer
hope this helps
