Answer:
+
= 0
Step-by-step explanation:
Based on 2x - 9y - 12 = 0
-9y = 12 - 2x
9y = -12 + 2x
y = 
Therefore...
5x - 4y + 7 = 0
5x - 4(
) + 7 = 0
5x +
-
+ 7 = 0
+
= 0
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?
The answer of that question is a lot, idk
Answer:
25%
Step-by-step explanation:
Lets figure out how many students total in Lorenzo's grade:
7 students + 21 students = <u>28 total students</u>
<u />
We know that we can find the percentage by dividing our value by the total amount and multiplying it by
, which is 1. (Multiplying by 1 does not change anything, which is why we choose to do this.)
Taking our known values,

<em>Therefore, </em><em>25%</em><em> of students voted for the athlete.</em>
