Answer:

x = 25

Step-by-step explanation:

The two angles form a straight line which is 180 degrees

2x+10 + 4x+20 = 180

Combine like terms

6x+30 = 180

Subtract 30 from each side

6x+30-30 = 180-30

6x = 150

Divide by 6

6x/6 = 150/6

x=25

Subtract, 8 3/8 - 10 1/6

IRISSAK [1]

$8\frac{3}{8} = \frac{67}{6} \\ 10\frac{1}{6} = \frac{61}{6}$

$8\frac{3}{8} - 10\frac{1}{6}$

$convert$ them to: $\frac{67}{8} - \frac{61}{6}$

$\frac{67}{8} - \frac{61}{6} = \frac{-43}{24}$

Your $answer$ : $-1\frac{19}{24}$

Good luck on your assignment & enjoy your day
