A father is 38 years old. his sons are 13 and 5 years old, and his daughter is 8 years old. In how many years will the father be
nalin [4]

Answer:

6 years

Step-by-step explanation:

So each person's age can be represented as a linear equation, since each year our age increases by 1. It can be represented in the slope-intercept form: y=mx+b. The slope in this case is going to be 1, since the time is going to be years, and each year everyone's age goes up by 1 (of course if you're still alive...) and y-intercept in this case represents their current age.

So the father can be represented as: y=x+38

The sons can be represented as: y = x+13 and y=x+5

The daughter can be represented as: y=x+8

So adding up all his children you get:

(x+13)+(x+5)+(x+8)

This gives you the equation:

3x+26

Now set this equal to the father's age to solve for x (in this context it's years)

3x+26=x+38

Subtract from both sides

2x+26=38

Subtract 26 from both sides

2x=12

Divide both sides by 2

x=6

So in 6 years the father will be the same age as his children put together

Mr. Beebe asks the question in lines 6-7 ("Does . . .
shusha [124]

Correct option is D. Mr. Beebe asks the question in lines 6-7 ("Does . . .

quietly") primarily in order to note an apparent inconsistency.

Mr. Beebe sounds cynical (though he says he is not) of the fact that Lucy Honeychurch is someone who plays the piano beautifully and likes to live quietly. He believes that one these both qualities will 'mingle'. In the given context, it seems like Beebe believes that a person can not be both: good at music and like to live quietly. He thinks that it is reflects an inconsistency in Lucy's personality. Thus D is the best answer.

The lines of passage were -

Does it seem reasonable that she should play piano so wonderfully, and live so quietly? I suspect that someday she shall be wonderful in both. The water-tight compartments in her will break down,
