The answer to the question is 2
Step-by-step explanation:
We have got the lines :

Both lines intercept the x-axis in the point :

In all point from x-axis the y-component is equal to 0.

We replace the I point in the lines equations:

From the first equation :

From the second equation :

Then 
Finally :

y = ax + b and y = cx + d have the same x-intercept ⇔ad=bc
10*30=300
10*4=40
6*30=180
6*4=24
add them up: 300+40+180+24=544
Answer:

8.85 original weight
Consecutive numbers. X
X+1
X+2
Add them together. 3x + 3 = 33 + x
-3 -3
3x = 30+ x
-x. -x
2x = 30
X = 15
