Answer:
B= -6x/5
[Step by Step.]
2x + 3b/9 = x - b/2
Step 1: Add 1/2b to both sides.
1/3b + 2x + 1/2b = -1/2b + x + 1/2b
5/6b +2x = x
Step 2: Add -2x to both sides.
5/6b + 2x + -2x = x + -2x
5/6b = -x
Step 3: Divide both sides by 5/6.
5/6b -x
------- = -------
5/6 5/6
b = -6x/5
Hope this helped!
Answer C
to calculate mean absolute deviation, we need to use the formula = (∑|x-mean|)/n
where x is each term given in data set
n is number of terms = 7
mean = sum of terms / n = (112+134+150+98+120+68+116)/7 = 114
now find (∑|x-mean|) = 138
MAD = (∑|x-mean|) / n = 138 /7 = 19.714 = 20
Answer:
x = 1 y = 2
Step-by-step explanation:
you add the equations and get 3x equals 3 divide x by 3 get 1 x equals 1 substitute x in the first equation for 1 1 plus y equals three subtract one and y equals 2
Variable costs are costs that change as the quantity of the good or service that a business produces changes.
