Answer 1
Answer: b. might be 4/x=3/4. I'm no mathematician, but if it's wrong, blame my teacher. d would probably be something. I'm no good with numbers.

How do you do 3b+7.1=2.5b+11.5

Answers

3b+7.1=2.5b+11.5

First, you'd take 2.5b and subtract it from 3b

3b-2.5b+7.1=11.5

Simplify:

.5b+7.1=11.5

then, you would take 7.1, and since it is positive, subtract it from 11.5

.5b=11.5-7.1

Simplify:

.5b=4.4

Lastly, you'd take 4.4 and divide it by .5, leaving the unknown factor alone.

b=4.4/.5

Final answer:

b=8.8

Can someone show me how to do Mean absolute deviationWhat is the means-to-MAD ratio of the two data sets, expressed as a decimal?
Data set Mean Mean absolute deviation (MAD)
1 10.7 2.4
2 13.7 2.5

Answers

To find the mean of a set, add up all of the numbers and divide by how many numbers you have. For the first set:
\mu=\frac{10.7+2.4}2=\frac{13.1}2=6.55
For the second set:
\mu=\frac{13.7+2.5}2=\frac{16.2}2=8.1

To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean.
For the first set: 
MAD=\frac{|10.7-6.55|+|2.4-6.55|}2=\frac{4.15+4.15}2=\frac{8.3}2=4.15
For the second set:
MAD=\frac{|13.7-8.1|+|2.5-8.1|}2=\frac{5.6+5.6}2=\frac{11.2}2=5.6
Note that when you only have two data points the mean is directly between them, which is why the distances are the same.

The means-to-MAD ratio is simply that, divide one by the other and that's it.
For the first set:
6.55/4.15=1.57831325
For the second set:
8.1/5.6=1.44642857

angle y and angle x form vertical angles. Angle y forms a straight line with the 80 degree angle and the 60 degree angle. Write and solve an equation to determine the measure of angle x

Answers

If angle y and angle x form vertical angles, then they ARE vertical angles.  Vertical angles have the SAME degree measure.  If angle y forms a straight line with the 80 degree angle and the 60 degree angle, this means that adding angle y, the 80 degree angle, and the 60 degree angle gives you a straight line.  A line is 180 degrees.  So, angle y's measure=180-(80+60).  Since measure of angle x equals measure of angle y, the equation is m<x=180-(80+60).

Let's solve.  m<x=180-(80+60).  m<x=180-140.  m<x=40 degrees.

Answer: m<x=180-(80+60); m<x=40 (degrees)
