x-1, x, 0.5x, 0.5x

Forgot the units. Its all in km

Correct but there are units missing (km).

(x+1)+(x+8)+(x-11)+1Check x+1+x+8+x-11+1

(km)

Its correct. But presentation is for checking only. No conclusion

x-5 km, x+5 km, x-10 km, 9 km

Correct.

x km, x/2 km, (x/2-1)km, x km

Ja

0.5x,1x,0.5x,1x + (-1)kmcheck 0.5x+0.5x+1x+(-1)=(3x-1)km

0.5x+0.5x+1x+1x+(-1)

1X + (-1)km shld be (X-1)km

Thanksss

5,x+7,x-13,x

km

It's correct!

0.5x, 0.5x, x-1,x

You are right.

OH!You forgot the (km) so you are wrong!

x km + x km + x+10 km+ x-9 km

Your answer is wrong Jian Qing. x km+x km is 2x km. 2x km + (x+10 km) is 3x +10 km. 3x + (x-9 km) is 4x + 1 km.

(X-10000, X-20000 , X+30000 , X-1)

3RD Value is 3000

I mean 30000

correct

the lengths of the 4 roads are : x - 5km, x km, x + 1km, 3km

Correct-a-mungo!

(x-8)+x+x+7=3x-1

correct... but missed out "km" :|

and never state separate four lengths

x km + x km + 20km + x - 19km = 3 x -1

Correct. But x-19km should be in brackets and answer is missing the units.

x-1,2/3x,2/3x,2/3x

You're missing out on your units and the brackets for the fractions.

x+1, 0.5x, x-2, 0.5x

u are correct!B)

KM

0.5x+0.5x+x+x+(-1)=(3x-1)

just write x-1...

but still correct

0.75x, 0.75x, 0.5x, x-1

all okay. Units? km/cm/m/$/min?

0.5x KM, 0.5x KM, 0.5 x KM, 1.5 x KM -1check: 0.5x +0.5x +0.5 + 1.5x-1 = 3x-1

*KM

*** 0.5xu missed the x in 0.5, so is incorrect

x+x+100km+x-99

ITS CORRECT

But missing units

(x+1)+(x+7)+(x-10)+1 (km)

right

0.5x , 0.5x , 0.5x , 1.5x-1km

Hng anh, your answer is correct
