Chapter 5: Algebra... Different "Faces" of Algebra (II)

The total length of 4 roads is (3x - 1) km.
What are the possible lengths of the 4 roads in kilometres?

e.g. The length of the 4 roads are: x km, x km, x-7 km, 6 km
Check: x + x + (x - 7) + 6 = 3x - 1

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

1. The Lengths of the 4 roads
1 ~ x
2 ~ x
3 ~ x-8
4 ~ 7

4. x+x+(x+6)-7

1. 1st - x
2nd- x
3rd- (x+6)
4th- -7

cannot be negative

3. A ROAD CAN NEVER BE -7!!! NO LOGIC. :D

4. How You Created a -7 Road?

5. It is not possible to have a road that is -7 in length.

8. The length of the 4 roads are: (1/2)x km, x km, (x-1) km, (1/2)x km
Check: (1/2)x km + (1/2)x km + x km + (x-1)km
=(3x-1)km

9. Road 1 - 1.2x km

1. 1.2x km + 0.7x km + 1.1x km + 1km

2. no negative

3. You Don't have -1

4. Your current total is (3x+1)km not (3x-1)km

5. this does not add up to (3x-1)
pootis!

6. There is no negative number (-1).

7. Road 1 - 1.5x km

1.5x km + 1.5x km + -1km + 2km

8. where's "-1 " ???

9. Ryan shut up u the pootis.

10. so mean......
by the way..... what is "shut up u the pootis?"

10. x+x+(x+19)-20

11. The length of the 4 roads are: x km, x km ,x-9km, 8km
x+x+(x-9)+8=3x-1

2. where ur question

14. x-7+(1/2)/x+(1/2)/x+x+6

16. x/2 + x/2 + x + (x-1)

2. the length of the roads are..........
x,x,(x+2) and x-1
check x+X+(x+2)+(x-1)=(3x-1)
i think.........
this is gonna be derped up again

20. The length of the 4 roads : 2x , x-8 , 6, 1
2x+(x-8)+6+1

21. The length of the 4 roads are 2x km,x-5 km,2km,2km
Check:2x+(x-5)+2+2

22. tha length of the 4 roads are (x)km,(x)-8km,(x)-8km,15km
check (x)+[(x)-8]+[(x)-8]+15=[3(x)-1]

23. ((x+x+x)-1)KM
