Answer:
QS is 34
Step-by-step explanation:
We find x first. We set each side equal to each other to do so.
5x-3=21-x
6x=24
x=4
Next we find QS value. We add each side.
5x-3+21-x
4x+18
Then we plug in x to find numeric value.
4(4)+18
34
Answer:
QS is 34
Step-by-step explanation:
R is the midpoint of QS
So, QR= RS
(QR = 5x-3 and RS =21-x)
QR= RS
Plug in QR and RS
Add x on both sides
Add 3 on both sides
Divide by 6 on both sides
Plug in 4 for x
