Okay so i would do this with a logarithm.
5^(2x) = 28
take the log of both sides
log5^(2x) = log28 and because of this log rule: logA^n = nlogA
(2x)log5= log28
then divide by log5 on both sides
2x = log28 / log5
and divide by 2
x = (log28 / log5) /2
this can be found with a calculator:
x= about 1.03521...
round that to whatever the question says to
1:2
because red:black = 10:20 and simplifies to 1:2

<h2>D. This is an experiment with blocking </h2><h2 />
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
M = y2 - y1 / x2 - x1
= - 9.75 - 6.75 / 3.33 - ( -8.5 )
= - 16.5 / 11.83
=> y= - 16.5 / 11.83x +b
6.75 = - 16.5 / 11.83 ( -8.5) +b
6.75 = 11.86 +b
=> b = - 5.11
Answer : y= - 16.5 / 11.83x - 5.11
