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

8The value of QS is 30
QR = 5x-3
QR = 5x-3RS =21-x
Since, R is the midpoint of QR and RS ;
THEN ; = QS = QR + RS
5x - 3 = 21 - x
Solve for x
Collect like terms
5x + x = 21 + 3
6x = 24
Divide both sides by 6
x = 24 / 6
x = 3
QS = 5x - 3 + 21 - x
QS = 4x + 18
Put x = 3 in the equation :
QS = 4(3) + 18
QS = 12 + 18 = 30
The value of QS = 30
