4vp2

Answer:

tl;dr: a = b(4) + 6

Step-by-step explanation:

To start, we should first find Uncle Frank's age currently. We can do this by multiplying 4 times 11 [tex]\frac{1}{2}[/tex].

[tex]4[/tex] · [tex]11 \frac{1}{2}[/tex] [tex]=[/tex] [tex]46[/tex]

So now that we know that Uncle Frank is 46 years old, all we have to do is add 6 more years, and it will be how old he will be in 6 years.

[tex]46[/tex] + [tex]6[/tex] = [tex]52[/tex]

Uncle Jack will be 52 years old in 6 years.

Now, we write the expression. Let a represent Uncle Jack's age while b represents Cole's age.

a = b(4) + 6
