The largest possible number would be if they only knew one language, so the answer would be 32
Hope this helps

I'm pretty sure this is a trick question. I also think the answer is 32.

Let the number x.

Then the number divided by 2 gives

$\frac{x}{2}$

Subtract 3.8 from the quotient gives

$\frac{x}{2}-3.8$

Hence,

$\frac{x}{2}-3.8=7$ $\begin{gathered} \frac{x}{2}-3.8=7 \\ \frac{x}{2}=7+3.8=10.8 \\ \Rightarrow x=2\times10.8=21.6 \end{gathered}$

x = 21.6

Answer:

-5

Step-by-step explanation:

Once you get y alone the equation will look like this y=-7/4x-5.

The slope intercept form dictates that y=mx+b, with b being the y-intercept, so -5 is b, therefore the y intercept.
