Answer:
x = 9.6
Step-by-step explanation:
The figure is a similar figure and the quadrilaterals (4 sides) created are related to each other by the same ratio.
So we can say:
8 goes with x as (8+12) goes with 24
We can setup a ratio and solve for x:
So x = 9.6
Step 1: Simplify both sides of the equation.
3(x−5)−5=23
(3)(x)+(3)(−5)+−5=23(Distribute)
3x+−15+−5=23
(3x)+(−15+−5)=23(Combine Like Terms)
3x+−20=23
3x−20=23
Step 2: Add 20 to both sides.
3x−20+20=23+20
3x=43
Step 3: Divide both sides by 3.
3x
/3 = 43

Answer: 8+(x÷39) or (x÷30)+8
Mean = 8
The mean is the average number in a sequence. To find the mean we can simply use the following equation
(Sum of all numbers) ÷ (Amount of numbers)
The sum of the given numbers is <em>160</em>
The amount of numbers is <em>20</em>
<em />
So the mean = 160 ÷ 20 or 8.
