H/j=15 solve for j <br> Please answer

Katyanochek1 [597]

Hey!

Let's write the problem,
$\frac{H}{j}=15$
Multiply both sides by $j$ in order to undo the fraction.
$\frac{H}{j}j=15j$
$H=15j$
Let's switch sides so that we end up with $j$ on the left side.
$15j=H$
Divide both sides by $15$ .
$\frac{15j}{15}=\frac{H}{15}$

Our final answer would be,
$j=\frac{H}{15}$

Thanks!

PLSS give me the answer for the B and C!! ( there two different questions)

Rzqust [24]

Answer:

Circumference Formula :

$2\pi r$

$\frac{120}{360}$

This is the ratio we can work out:

$\frac{given \: angle}{revolution} = ratio$

$arc = ratio \times circumference$

$22 = \frac{120}{360} \times 2 \times \frac{22}{7} \times r$

$22 = \frac{44}{21} x$

$x = 22 \div \frac{41}{21}$

$x = \frac{21}{2}$
