$(2x + 10) + (4x + 20) = 180^{o}$

$6x + 30 = {180}^{o}$

$6x = {180}^{o} - 30$

$6x = {1 50}^{o}$

$x = {150}^{o} \div 6$

$x = {25}^{o}$

sum of three numbers, a, b, c is 180.

a=2x-11

b=x-4

c= ?

c = 180 - (2x-11) - (x-4)

= 180 -2x+11 - x+4

= 180 + 11 + 4 -2x -x

Using the number line shown, subtract 1 2/6 from 4 4/6.

Soloha48 [4]

Hey there!

$\bold{1\frac{2}{6}-4\frac{4}{6}}$

$\bold{1\frac{2}{6}=1\frac{1}{3}=\frac{4}{3}}$
$\bold{4\frac{4}{6}=4\frac{2}{3}=\frac{14}{3}}$
Problem becomes: $\bold{\frac{4}{3}-\frac{14}{3}}$
To solve our new problem $\uparrow;\downarrow$
$\bold{4-14=-10}$
The $\bold{3's}$ stay the same because the same
$\bold{\rightarrow=\frac{-10}{3}}$
$\boxed{\boxed{\bold{Answer:\frac{-10}{3} (or)=-3\frac{1}{3}}}}$

Good luck on your assignment and enjoy your day!
