$\frac{1}{2} k-\frac{3}{5}$

Step-by-step explanation:

Step 1: Define expression

$\frac{2}{5} k-\frac{3}{5} +\frac{1}{10} k$

Step 2: Change denominators to like terms

$\frac{4}{10} k-\frac{3}{5} +\frac{1}{10} k$

Step 3: Combine like terms

$\frac{5}{10} k-\frac{3}{5}$

Step 4: Simplify

$\frac{1}{2} k-\frac{3}{5}$

x=18, m∠1=140, m∠2=40

Step-by-step explanation:

m∠1 and m∠2 will equal up to 180

7x+14+2x+4=180

Combine like-terms

9x+18=180

Subtract 18 from both sides.

9x=162

Divide both sides by 9

x=18

Then plug in 18 for x in the angle measures

7(18)+14=140

2(18)+4=40
