Answer:

Easy! Put away your slide ruler! Just take one painter. He takes one hour to paint 1/3 of a wall.. Boy these guys must be in the union for they are really slow.. so lets assume one painter painted all 8 walls. That is a lot of cigarette breaks, it would take him 24 hours to paint all 8 walls…. But he has 3 other buddies… yea! so 4 into 24 = 6 Hours!

20pts. Find the measure of ∠BEC. A) 10° B) 60° C) 80° D) 100°

Schach [20]

<h2>Explanation:</h2><h2></h2>

The figure to this problem is attached below. We know that angles ∠AEG and ∠GEC are supplementary, so:

∠AEG + ∠GEC = 180°

∠AEG = 8x°

∠GEC = (4x + 60)°

8x° + (4x + 60)° = 180°

(12x + 60)° = 180°

12x + 60 = 180

12x = 180 - 60

12x = 120

x = 10

∠AEG and ∠BEC are vertical angles, so they are congruent:

∠BEC = 8x°

∠BEC = 8(10)°

∠BEC = 80°

yarga [219]

Answer:

x=0

Step-by-step explanation:

You can substitute 2-6y in for x to create

9y +2(2-6y) = 3

9y + 4 -12y = 3

-3y = -1

y=1/3

Then plug in y for x=2 -6y

x= 2-6(1/3)

2-2=x

x=0
