Answer:

d. 20.5

solve:

$\hookrightarrow BR: 27 - - 14$

$\hookrightarrow BR: 41$

Given A is the midpoint of BR.

Therefore:

$\hookrightarrow AR/BR: \frac{41}{2}$

$\hookrightarrow AR/BR: 20.5$

Answer:

20.5

Step-by-step explanation:

the formula for the midpoint = (x1 + x2)/2, (y1 + y2)/2.

put in x and y for

(-14+27)/2,(0+0)/2

13/2,0/2

6.5,0

so make a new line from (6.5,0) to (27,0)

27-6.5=20.5

mr john has a son and a daughter , the son being 4 years older than daughter.Five years ago the age of mr john was 23 years more

jeka94

First, let us define our variables.

Let

x = age of the father

y = age of the son

z = age of the daughter

5 years ago..

(x – 5) = age of the father

(y – 5) = age of the son

(z – 5) = age of the daughter

After 18 years...

(x + 18) = age of the father

(y + 18) = age of the son

(z +18) = age of the daughter

From the first condition

y = z + 5 à eqn 1

5 years ago

(x-5) = 23 + (y-5) + (z-5)

x –y –z = 18 à eqn 2

after 18 years

(x+18) = 17*[(y +18 –z – 18)]

x – 17y + 17z = -18 à eqn 3

solving the 3 equations simultaneously

x = 67

y = 27

z = 22
