Solve for x I need help again :/

Nostrana [21]

The Angles depicted 38° and (6x + 2)° are equal because they form vertical opposite Angle pair.

so,

6x + 2 = 38

6x = 38 - 2

6x = 36

x = 36 ÷ 6

x = 6

What is 5 1/6 minus 1 1/3

zaharov [31]

We must find the common denominator.

LCM(6, 3) = 6

$5\dfrac{1}{6}-1\dfrac{1}{3}=5\dfrac{1}{6}-1\dfrac{1\cdot2}{3\cdot2}=5\dfrac{1}{6}-1\dfrac{2}{6}=(5-1)+\left(\dfrac{1}{6}-\dfrac{2}{6}\right)=4-\dfrac{1}{6}=3\dfrac{5}{6}$

or other method of calculating the difference

$5\dfrac{1}{6}-1\dfrac{2}{6}=4\dfrac{6+1}{6}-1\dfrac{2}{6}=4\dfrac{7}{6}-1\dfrac{2}{6}=(4-1)+\left(\dfrac{7}{6}-\dfrac{2}{6}\right)=3\dfrac{5}{6}$
