Answer:
1. MO=14 units
2. M=3
3.X=5
Step-by-step explanation:
1. The length is just how many units between each point
2. Find the average of the two points (use absolute value)
(|-4|+10)÷2=(4+10)÷2=14÷2=7, the midpoint is 7 units from each endpoint. so 10-7=3
3. the length of the line ac=10x, the parts are 12 and 8x-2 set up an equation
10x=12+8x-2 combine like terms
2x=10 divide both sides by 2
x=5
