Answer:
x = 42,33°
Step-by-step explanation:
3x + 1° + 52° = 180° [<em>angles</em><em> </em><em>on</em><em> </em><em>a</em><em> </em><em>straight</em><em> </em><em>line</em><em>]</em>
3x + 53° = 180°
3x = 180° - 53°
3x = 127°
<em><u>divide</u></em><em><u> </u></em><em><u>b</u></em><em><u>o</u></em><em><u>t</u></em><em><u>h</u></em><em><u> </u></em><em><u>sides</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>3</u></em>
x = 42,33°
A:
An independent variable could be how long she works. (Well it's not really independent I guess... Sorta depends.)
A dependent variable could be how much money she makes, depending on how long she works.
B:
Umm, like:
(1, 7)
If 1 was how many hours she worked and $7 is how much money she made, and therefore x would be how many hours she worked and y would be how much total money she made.
(2, 14)
(3, 21)
C: An equation would be 7x = y.
