Answer:
100 students
Step-by-step explanation:
10% of students in 7th grade ----- 10 students
<em>Divide</em><em> </em><em>by</em><em> </em><em>1</em><em>0</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
1% of students in 7th grade ----- 10 ÷10= 1 student
<em>×</em><em>100</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
100% of students in 7th grade ----- 1 ×100= 100 students
Step-by-step explanation:
I'm not sure what the ordered pairs due to you not providing them, but I can tell you the best way to see if they are solutions.
The best way to do so is by substituting the x and y values into the equation.
For example, if you had the ordered pair (5,2), then you would put the x coordinate in place of x and the y coordinate in the place of y.
Like so:
2 = -2(5)+6
The way you know if its a solution is if they equal the same thing.
Solution example:
2 = 2
Non-solution example:
5 ≠ 3
