Question

quickly, can someone answer all of the unanswered question correctly in the picture below.plz

Answer 1

inversely proportional
4 ---------- 12
12 -------- x

$\frac{4}{12} = \frac{x}{12}$
$\boxed{x = 4}$

---------------------------------------------------------------

inversely proportional
6 -------------- 10
18 ------------ x

$\frac{6}{18} = \frac{x}{10}$
$18*x = 6*10$
$18x = 60$
$x = \frac{60}{18}$
$\boxed{x \approx 3,3}$

----------------------------------------------------------------

inversely proportional
4 ---------- 10 ----------- 60
30 -------- 10 ----------- x

$\frac{4}{30} * \frac{10}{10} = \frac{x}{60}$
$\frac{40}{300} = \frac{x}{60}$
$300*x = 40*60$
$300x = 2400$
$x = \frac{2400}{300}$
$\boxed{x = 8}$
