Please help me i need to solve for RS
Sonbull [250]

Answer:

<h2>         RS = 47</h2>

Step-by-step explanation:

RV=VU and SW=WT    ⇒    VW=\dfrac{RS+UT}{2}

So:

3x+5=\dfrac{2x+15+6x-37}{2}\\\\3x+5=\dfrac{8x-22}{2}\\\\3x+5=4x-11\\^{\qquad-5\qquad-5}\\3x=4x-16\\^{-4x\qquad-4x}\\-x=-16\\^{\div(-1)\quad\div(-1)}\\x=16\\\\RS=2x+15=2\cdot16+15=32+15=47

Solve:<br><br> 7 = x + 12<br> A) -19 <br> B) -5 <br> C) 4 <br> D) 5
DaniilM [7]

<em><u>Hello, there! :)</u></em>

<u><em>Answer:</em></u>

<u><em>x=-5 </em></u>

<u><em>B. -5</em></u>

<u><em>*The answer must have a negative sign.*</em></u>

Step-by-step explanation:

Definition of subtraction property of equality.

Subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

a-c=b-c

First, you had to switch sides.

x+12=7

Then, you subtract by 12 from both sides of an equation.

x+12-12=7-12

And finally, simplify or solve.

7-12=-5

x=-5

Hope this helps!

Thanks!
