Answer:
Step-by-step explanation:
It takes Lucas 3 hours to cycle from his home to his friend’s village:
3 hours • (a certain speed) = distance in miles
If he travels 5mph slower, it will take him 1.5 hours longer:
4.5 hours • (the same speed - 5mph) = the same distance in miles
4.5 • (x - 5) = 3x
4.5x - 22.5 = 3x
1.5x = 22.5
x = 15mph
3hours • 15mph = 45 miles
Hello,
|x+4|=3x-5
if x+4>=0 then
|x+4|=x+4
x+4=3x-5
2x=9
x=9/2
else
x+4<0 : x<-4
|x+4|=-(x+4)
-(x+4)=3x-5
-x-4=3x-5
4x=1
x=1/4 : to exclude since x<-4
end if
Only one solution : x=9/2
