Suppose the number of students in one of the classes is :

$x$

So ;

$Mr.Lopez \: \: had \: \: \frac{92.5}{100}x \\$

_________________________________

$Mrs.Foster \: \: had \: \: \frac{19}{20} x \\$

So :

$Mrs.Foster \: \: had \: \: \frac{19 \times 5}{20 \times 5} x \\$

$Mrs.Foster \: \: had \: \: \frac{95}{100}x \\$

$Ms.Kelly \: \: had \: \: 0.9x$

$Ms.Kelly \: \: had \: \: \frac{9}{10} x \\$

$Ms.Kelly \: \: had \: \: \frac{90}{100} x \\$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Compare :

$\frac{95}{100} x > \frac{92.5}{100} x > \frac{90}{100} x \\$

Thus :

$Mrs.Foster’s \: \: class \: > \: Mr.Lopez’s \: \: class \: > \: Ms.Kelly’s \: \: class \\$

I am very confused and don't know where to start!

stealth61 [152]

Well, lets start with #3!
<1 is equivalent to <3 because they are vertical angles.
This means that <2 and <4 are congruent because they are vertical angles. We know that a straight line is 180 degrees. So, <1 and <2 added together will equal 180, therefore, <2 is ___________

Since the two lines are parallel, any angle on the other side is congruent, as long as that angle is in the same place as the other. So, we can see that <1 and <7 are in the same place, just moved down. So, <7 is __________.

How do you change an equation into the formula y=mx+b?

Molodets [167]

Basically, this equation is called the "slope intercept form" and to change into into that, you must simplify the equation.
