1192.64-819.73 is 372.91
so... if we take 1192.64 to be the 100%, how much is 372.91 in percentage then?
4e - 6e - 5 = 15
Begin by combining like terms:
4e - 6e = -2e.
The equation is now simplified.
Now, it is time to find the value of the variable.
-2e - 5 = 15
Step 1: Add 5 to both sides.
We now have -2e = 20.
Step 2: Divide both sides by -2 to isolate the variable.
-2e / 2 = e; 20 / -2 = -10.
Therefore, e = -10.
If 3 =
, then we know 9 =
because 9 is 3 squared.
can be simplified to
So now we know
=
·
Since
and
have the same base, we can express it as a single term by adding the exponents together.
So the answer is C)

For your question: "A teacher wants to investigate whether listening to music while taking a math test increases scores. He instructs half
of his 36 students to listen to music while taking a test and the other half to not listen to music during the test. To
determine who listens and who does not, the teacher identifies the two students who scored highest on the last test
and randomly instructs one to listen to music and one to not. The teacher does the same for the next two highest-
scoring students and continues in this manner until each student has their instructions. Which of the following best
describes this plan?"
The answer is D
