Answer:

Step-by-step explanation:

RV=VU and SW=WT means $VW=\frac{RS+UT}{2}$

So:

$3x+5=\dfrac{2x+15+6x-37}{2} \\^{\qquad\times2\qquad\qquad\qquad\qquad\times2} \\6x+10=8x-22\\^{\qquad-10\qquad-10}\\6x=8x-32\\^{-8x\qquad-8x}\\-2x=-32\\^{\div(-2)\quad\div(-2)}\\x=16\\\\RS=2x+15=2\times16+15=32+15=47$

None of your answers are correct

all you have to do it look at what place the value underlined

the 5 is in the 100 thousands place this means that the value is 500,000
