Answer:

Step-by-step explanation:
15 can go into both 45 and 150 so you divide both into that
45/15 is 3
150/15=10

Answer:
3.5 meters
Step-by-step explanation:
- 1:4 = x:14 ; where x is the unknown length of A
- 1/4 = x/14 (Cross multiply)
- Giving us, 4×x = 14×1
- 4x = 14 (Divide both sides by co-efficient of x, which is 4)
- x = 14/4
- x = 3.5
- Therefore, the length of A is 3.5 meters.
10x + 35
If it is just the sum then it is this.
2x+18+1-1 works if that's all you want
