When you have to divide by a fraction, you have to multiply the other number by the fraction's reciprocal.

8 = 3/4 w Divide by 3/4

w = 8/(3/4)

w = 8/ (3/4) = 8 x 4/3 Multiply by the numerator and divide by the denominator.

w = (8 x 4) / 3

w = 32 / 3

w = 10 2/3

You want to isolate the variable w so you want it by itself. To do so with a fraction multiply both sides by the fraction's denominator...
8(4)=3w
32=3w
Now you want to divide both sides by 3
32/3=w
10.67=w
This should be your answer :)

Find the value of k so that 48x-ky=11 and (k+2)x+16y=-19 are perpendicular lines.

Rufina [12.5K]

Answer: k = -1 +/- √769

Step-by-step explanation:

48x - ky = 11

-48x -48x

-ky = -48x + 11

$\frac{-ky}{-k} = \frac{-48x}{-k} + \frac{11}{-k}$

$y =\frac{48x}{k} - \frac{11}{k}$

Slope: $\frac{48}{k}$

*************************************************************************

(k + 2)x + 16y = -19

- (k + 2)x -(k + 2)x

16y = -(k + 2)x - 19

$\frac{16y}{16} = -\frac{(k + 2)x}{16} - \frac{19}{16}$

$y = -\frac{(k + 2)x}{16} - \frac{19}{16}$

Slope: $-\frac{(k + 2)}{16}$

**********************************************************************************

$\frac{48}{k}$ and $-\frac{(k + 2)}{16}$ are perpendicular so they have opposite signs and are reciprocals of each other. When multiplied by its reciprocal, their product equals -1.

$-\frac{(k + 2)}{16}$ * $\frac{k}{48}$ = -1
