Answer:
The distance between the origin and the given point is 13.9283 units.
Step-by-step explanation:
The coordinates of origin are (0,0,0)
We are given a point R(9,7,80
The distance formula:
, where
are coordinates of one point and
are coordinates of other point.
Putting the values as:

We get d = 
d = 
d = 13.9283
Thus, the distance between the origin and the given point is 13.9283 units.
1. 6/7÷2/7 = 3
2. 4/5÷2/5 = 2
3. 4/7÷2 = 2/7
4. 12/13÷3 = 4/13

Solution
3(-x+(2x+1))=x-1
3(x+1)=x-1
3x+3=x-1 collect like terms
3x-x=-1-3
2x=-4 divide both side by 2
x=-4/2=-2
Answer:
2
