what i would do is implant some number under 5 for the X's.
Then work it out as if 3 was x so for instance -4(8-3x3)
Ok, im guessing that this is all about mean
First mean is just adding everything up for example:
5+5+10+10+5
so the answer is 35, but that isnt completely finished you need to divide 35 by 5, or how many numbers were added then you get the mean for my example the mean is 7

ACTUAL PROBLEMS
1. 10+15+14+8+18+11+12+12+10+10+17+16 = 153
153/12= 12.75
2. 16.4+17.1+17.4+18.1= 69 B)
69/4=17.25
3. 11+15+19+17+23+20+17+13+18+21=174
174/11=15.8181818182
4. 21+25+36+16+32= 130
130/5=26

I would assume all of them since they are all the same, here is an example of exponential decay : Write an equation for the following statement, Merida has has $200,000 in a stock market which is decreasing by 1% annually.
f(x) = 200000(.99)^2
Comment if you need me to explain why this is the equation
Answer:
Area = 32 square inches
Step-by-step explanation:
It is given that ,
1). an isosceles right triangle with a perimeter of 27 inches
Then the base and height are equal
2). the longest side measures 11 inches
<u>To find the smaller side</u>
Then sum of other 2 sides = 27 - 11 = 16
Base = height = 16/2 = 8 inches
<u>To find the are of triangle</u>
Area = 1/2 * Base*Height
Base = 8 inches and Height = 8 inches
Area = 1/2 * 8* 8 = 32 square inches
