Points O, A, B lie on the same line. OA = 12 cm, OB = 9 cm. Find the distance between the midpoints of segments OA and OB if: Po
12345 [234]
Short Answer: 1.5
Givens
OA = 12
OB = 9
O does not lie on AB

Argument
The order that these lines must be in is OBA. O is on your left, B is in the middle and A is on your right. 

Mark your distances as follows.
OB = 9
BA = 3

Mark the midpoint of OA = M1
Mark the midpoint of OB = M2

M1 = 12 / 2 = 6 so M1 is 6 units from O
M2 = 9/2 = 4.5

The distance between the two midpoints is 6 - 4.5 = 1.5
Answer M1 - M2  = 1.5 <<<<

Nice problem: Thanks for posting.

Show that x + y : x - y= 3 : 2
insens350 [35]

Answer:

x + y : x - y = (5/2+1/2) : (5/2-1/2)

x + y : x - y = 3 : 2

Therefore,  x + y : x - y= 3 : 2 is proved.

Step-by-step explanation:

Given

x + y : x - y = 3 : 2

As

x + y = 3

x - y = 2

Solving to find x and y

\begin{bmatrix}x+y=3\\ x-y=2\end{bmatrix}

x-y=2

-

\underline{x+y=3}

-2y=-1

\begin{bmatrix}x+y=3\\ -2y=-1\end{bmatrix}

solve for y

-2y=-1

Divide both sides by 2

\frac{-2y}{-2}=\frac{-1}{-2}

y=\frac{1}{2}

\mathrm{For\:}x+y=3\mathrm{\:plug\:in\:}y=\frac{1}{2}

x+\frac{1}{2}=3

x+\frac{1}{2}-\frac{1}{2}=3-\frac{1}{2}

x=\frac{5}{2}

so

x=\frac{5}{2},\:y=\frac{1}{2}

Thus,

x + y : x - y = (5/2+1/2) : (5/2-1/2)

x + y : x - y = 3 : 2

Therefore,  x + y : x - y= 3 : 2 is proved.
