(-5/6x+51/2)-(2/3x+4)
stiv31 [10]

Answer:

-1.5x + 21.5 (or (43-3x)/2)

Step-by-step explanation:

(-5/6x + 51/2) - (2/3x + 4)

<em>First, find the opposite of 2/3x + 4 because of the negative sign.</em>

-5/6x + 51/2 - 4/6x - 4

<em>Now combine -5/6x and -4/6x to get -9/6x or -3/2x</em>

-3/2x + 51/2 - 4

<em>Convert 4 into 8/2 since 51/2 is a fraction.</em>

-3/2x + 51/2 - 8/2

<em>Since the denominators of 51/2 and -8/2 are the same, just subtract 51 and 8 to get 43.</em>

-3/2x + 43/2

<em>-3/2x and 43/2 have the same denominator (2), so you can just put it like this (It's up to you!):</em>

(43-3x)/2

The answer to (-5/6 + 51/2) - (2/3x + 4) is -3/2x + 43/2 (or (43-3x)/2)

<em>Or you could put it like this (I converted both -3/2 and 43/2 to a decimal.)</em>

-1.5x + 21.5

KM and NP are parallel lines.<br><br> Which angles are alternate exterior angles?
suter [353]

Answer:

<MLJ and <NOQ

Step-by-step explanation:

Alternate exterior angles are angles that lie outside of the two parallel lines that are cut across by the transversal line, and are also alternating each other along the transversal

Considering the image and the options given, <MLJ and <NOQ are exterior angles that alternate each other. Therefore, they are alternate exterior angles.
