The answer is 20 since 1/5 of 20 is 4, and 20 + 4 = 24.

Answer:  The correct option is (B) n = 20.

Step-by-step explanation:  Given that when a number is added to 1/5 of itself, the result is 24. The equation that models this problem is given by

n+\dfrac{1}{5}n=24~~~~~~~~~~~~~~~~~~~~~~~~(i)

We are to find the value of n.

Solving equation (i), we have

n+\dfrac{1}{5}n=24\\\\\\\Rightarrow \dfrac{5n+n}{5}=24\\\\\Rightarrow 6n=5\times24\\\\\Rightarrow n=\dfrac{5\times24}{6}\\\\\Rightarrow n=20.

Thus, the required value of n is 20.

Option (B) is CORRECT.

5) Find the equation of the line going through the point (4,1) and<br> perpendicular to y = - 3x +7
vovangra [49]

Answer:

3y=x-1 OR y=⅓x-⅓

Step-by-step explanation:

Lets call the equation y=-3x+7 line l1

the other line passing through (4,1) l2

If two lines are perpendicular,then the product of their roots=-1

That is m(l1)×m(l2)=-1

Slope of l1=-3 therefore slope of l2=-1÷-3=⅓

Now that we have determined the slope of l2 we move on to find it's equation using the point-slope form

y-y1=m(x-x1)

y-1=⅓(x-4)

3y-3=x-4

3y=x-4+3

3y=x-1 OR y=⅓x-⅓
