Answer:
There are 200 students in the seventh grade.
Step-by-step explanation:
For equations like these, you have to use the is/of formula, which is:
Percent/100 = is/of.
Since you are trying to find how many students are in the seventh grade, this means that 52 <u><em>is</em></u> 26% of the total amount of students in the seventh grade. So, the formula would look like so:
26/100 = 52/n.
Next, you have to cross multiply, which means you would multiply 26 by n, and 52 by 100.
Then, you are going to have this left over from the cross multiplying:
5200 = 26n.
Divide 26 on both sides, leaving you with:
1n = 200, or n = 200.
Answer:

Step-by-step explanation:
-5/(4)^2
=-5/(4*4)
=-5/16
It depends on how much you made per hour of work. Missing information.
Answer:
The system has no solutions
Step-by-step explanation:
we have
-----> equation A
----> equation B
Isolate the variable y in the equation A
-----> equation A'
Isolate the variable y in equation B
------> equation B'
Compare the equations A' and B'
The lines have the same slope but different y-intercept
Are parallel lines
therefore
The system has no solutions
