He’s right For the answer
We would find the midpoint by applying the formula for determining the midpoint of a segment which is expressed as
Midpoint = (x1 + x2)/2, (y1 + y2)/2
From the given points,
x1 = 4, y1 = - 5
x2 = 6, y2 = 1
Midpoint = (4 + 6)/2, (- 5 + 1)/2
Midpoint = 10/2, - 4/2
Midpoint = 5, - 2
<u>Answer:</u>
- Sahil's mother = 42 years
- Sahil = 14 years
<u>Step-by-step</u><u> Explanation</u><u>:</u>
Let the age of Sahil's mother be x and the age of Sahil be y. Then according to question.
• Sahil's mother age = 3(Sahil's age)
➛ x = 3y -----------(1)
And according to second condition,
• Sahil's mother age + 5 + Sahil's age + 5 = 66
➛ x + 5 + y + 5 = 66
➛ x + y + 10 = 66
➛ x + y = 56 ----------(2)
Now substituting x = 3y in equation (2)
➛ 3y + y = 56
➛ 4y = 56
➛ y = 14
Then,
➛ x = 3(14) = 42
<u>Hence</u><u>:</u><u>-</u>
- Present age of Sahil's mother is <u>42 years</u> and Present age of Sahil is <u>14 years.</u>
