The answer for 4 is 17.5 I’m pretty sure
Any value of x must be less than -5 for n to be negative. (x<-5)
What exactly do you need help with??
28 = x + (2x - 5)
28 = 3x - 5
+5 +5
33 = 3x
/3 /3
11 = x
On number is 11, the other is 17.
Check:
11(2)=22-5=17
The magic triangle is D and S and T where D is over S and T so if D is over s and t u dived and if the question is looking for D you would multiply S and T so 8 is the S i'm guessing and 15 is the T so ur gonna be looking for D so D=120 S=Speed D=Distance and T=time
i hope i helped you good luck
