Subtracting 2 from the original equation moves the graphed line 2 units down.
Blake can do the work in 9 and part of work in 1 hour = 1/9
Ned can paint the same room in six hours, as well as do part of work in 1 hour = 1/6
If they do it together = 1/9+1/6=5/118, and they can do 5/18 part of work in hour = 1
So, they can do whole work in hours = 1/5/18=3.6
So if they do it together it will only take 3.6 hours.
Answer:
m∠B = 22°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so we have ...
120° +(x +16)° +x° = 180°
136 +2x = 180 . . . . . . . . . collect terms, divide by °
68 +x = 90 . . . . . . . . . . . divide by 2
x = 22 . . . . . . . . . . . . . . . subtract 68
The value of x tells us the measure of angle B.
m∠B = 22°
