jeka57 [31]
<span>Let x=smaller number 
Then x+5=larger number 
Now we are told the following: 
1/5(x+x+5)=x-5 multiply each side by 5 
x+x+5=5x-25 subtract 5x and also 5 from both sides 
x+x+5-5-5x=5x-5x-25-5 collect like terms
</span><span>-3x=-30 divide both sides by -3
x=10 smaller number 
x+5=10+5=15  larger number

1/5(10+15)=10-5

How do i do this? geometry
iren [92.7K]

Answer:

80?

The endpoints of a line segment are at the coordinates (–6, 3, 4) and (4, –1, 2). What is the midpoint of the segment?
natulia [17]

Answer:

( - 1,1,3 )

Step-by-step explanation:

Use the midpoint formula:

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}, \frac{z_1+z_2}{2} )

We want to find the midpoint of the line

that has endpoints.

(\frac{ - 6+4}{2},\frac{3+ - 1}{2}, \frac{4+2}{2} )

We simplify to get;

(\frac{ - 2}{2},\frac{2}{2}, \frac{6}{2} )

This finally gives:

( - 1,1,3 )

The correct answer is A.
