5x0.10 = 0.50
1.20- 0.50 = 0,70
it is 0.50 not 50
than it is x (number of nicks) times 0.05 =0.70
so he has 14 nicles
You can set it up like:
400/2.5 = 600/x; now cross multiply
400x = 2.5(600)
400x = 1,500; now divide both sides by 400 to isolate the x, and you get x = 3.75 hours
Start with x:
Since x and 57º make a straight line, x+57 = 180 (because a line is 180º). This says x=123º
Now for y:
Because lines m and n are parallel, y and 57º are alternate interior angles and have the same measure. y=57º
Finish with z:
Since y and z make a straight line, can you finish that one from here?
A. For each addition door she knocks on, her earnings increase by 10 dollars.
