If m angle KNM = (8x - 5)° and m angle MNJ = (4x - 19)° , find the measure of angle KNM. ​
Murrr4er [49]

Answer:

131°

Step-by-step explanation:

Since KNJ is a straight line,

∡KNM +∡MNJ= 180° (adj. ∡s on a str. line)

(8x -5)° +(4x -19)°= 180°

<em>Simplify:</em>

12x -24= 180

<em>+</em><em>2</em><em>4</em><em> </em><em>on </em><em>both </em><em>sides</em><em>:</em>

12x= 180 +24

12x= 204

<em>Divide</em><em> </em><em>both </em><em>sides </em><em>by </em><em>1</em><em>2</em><em>:</em>

x= 204 ÷12

x= 17

∡KNM

= (8x -5)°

= [8(17) -5]°

= (136 -5)°

= 131°

A pizza is divided into 30 equal pieces. Violet and Sophie each ate one sixth
erastovalidia [21]

Answer:

12.5 or 12 1/2 Slices left

Step-by-step explanation:

30 divided by 6 or (1/6) is 5

So,

Violet ate 5

Sophie ate 5 (same amount)

30 divided by 5 or (1/5) is 7.5

so we add 5+5+7.5 = 17.5 and subtract it from 30 to get our left over slices which comes up to

12.5 or 12 and 1/2 slices

hope this helps
