6-x-x=18
-x-x=18-6
-x-x=12
-2x=12
x=12/-2
x=-6
Check: 6- (-6)- (-6) remember - - = +
So basically it's 6+6+6=18

If R is the midpoint of QS,QR=5x-4 and RS=2x+2,find QS

VashaNatasha [74]

Answer:

First graph it out. Once you do that you can see that QR is the same as RS. So you can do the equation 5x-4=2x+2. Once you solve this out you would get 2.4. I'm just an advanced 7th grader, so you can redo the problem to make sure

Step-by-step explanation:

QS=2.4

Please help me answer this math question <br><br> 1/2(b-12)

Sever21 [200]

we have given an equation $1/2(b-12)$

we need to simplify the given equation.

the distributive property is used here $a(b+c)=ab+ac$

$1/2(b-12)=\frac{b}{12} -\frac{12}{2}$

if we simplify the terms

we get $\frac{b}{2} -\frac{6}{1}$ .
