Answer:
-6.25 tI am not sure if this can help you but this is what I got
Question 5, x could be either 6 or -1.
Step-by-step explanation:
RT^2=RS^2+ST^2
RT^2=16+9=25
RT=√25=5
The answer is 5
5n-2=n+18
Move n to the other side
Sign changes from +n to -n
5n-n-2= n-n+18
5n-n-2= 18
4n-2= 18
Move -2 to the other side
Sign changes from -2 to +2
4n-2+2= 18+2
4n= 18+2
4n= 20
Divide by 4 for both sides
4n/4= 20/4
Answer: n=5
