13-5m=4-6m show work please
Vesna [10]
First subtract 4 from both sides
13 - 4 - 5m = - 6m

then simplify
9 - 5m = - 6m

add -5 to both sides
9 = - m

since a variable shouldn't be negative the answer should be
m = - 9

(I prefer having the variable on the left side)

anthony bought an 8 foot board.He cut off 3/4 of the board to build a shelf,and gave 1/3 of the rest to his brother for an art p
e-lub [12.9K]
Convert your feet to inches.
So 8 times by 12 = 96 inches
if you have 3/4 of the board used. 
3/4= .75 
if you were to times 96 by .75 = 72 inches.
So you used 72 inches and you have 24 inches left

now do 1/3= .33
times .33 by 24= 8
8 inches is how long you would give to Anthony's brother.

vagabundo [1.1K]

a+b+c=180,  \text{ }c+e=180 \implies \\ a+b+c=c+e \implies \\ a+b=e\\

This result is actually true for any exterior angle. The exterior angle of a triangle is equal to the sum of the two remote angles, and above is a short proof of it.
