PLEASE HELP!! WILL GIVE BRAINLIEST ANSWER TO THE FIRST PERSON

Answer 1

Answer:

See below.

Step-by-step explanation:

So, from the figure, we can see that US is the combined length of UT and TS. In other words:

$UT+TS=US$

We are given their equations. Substitute them:

$(x-3)+(12)=(3x-11)$

And this is our answer to 4.

Now, solve for x. Add on the left:

$x+9=3x-11$

Subtract -3x from both sides:

$-2x+9=-11$

Subtract 9 from both sides:

$-2x=-20$

Divide both sides by -2:

$x=10$

So, for 5, the answer is 10.

And we're done!
