Answer:

$\frac{5}{192}$

Step-by-step explanation:

$\frac{3}{8} * \frac{2}{6} * \frac{4}{8} * \frac{5}{12}$

Multiply all numerators

3 * 2 * 4 * 5 = 6 * 20 = 120

Multiply all denominators

8 * 6 * 8 * 12 = 48 * 96 = 4,608

$\frac{120}{4608}$

Simplify

$\frac{5}{192}$

What is value of x? Please help! Will reward

vazorg [7]

x = 50

The angles shown are vertically opposite and thus equal

so 3x - 30 = 2(x + 10)

3x - 30 = 2x +20

subtract 2x from both sides

3x - 2x - 30 = 20

x - 30 = 20

add 30 to both sides

x = 20 + 30 = 50
