We are asked to find the length of
, which measures
. Using the segment addition postulate, we can add the two given expressions for
and
and make it equal to the expression for
.
We've found the value of
, but we aren't done yet. We need to plug in the value we got for
into the expression for
, which is
. Therefore,
. Hope this helped and have a great day!
4 16/16 This is the same as 5.

I'm thinking this is what the problem looks like:
. The first thing to do is to move the
over to the other side because it has a common denominator with the other side. Doing that and at the same time combining them over their common denominator looks like this:
. The best way to solve for x now is to cross-multiply to get 3(4-x)=-4(x-4). Distributing through the parenthesis is 12 - 3x = -4x + 16. Solving for x gives us x = 4. Of course when we sub a 4 back in for x we get real problems, don't we? Dividing by zero breaks every rule in math that there ever was! So, yes, the solution is extraneous.
Answer:
$8 per hour
Step-by-step explanation:
The unit rate is $ per hour
Divide the amount by 8 
= 8.5 hours
$68 ÷ 8.5 = $8 per hour
The only factors are 1 and 29
