Step-by-step explanation:
![\tt{30.16 = 17.56 + 5x}](https://tex.z-dn.net/?f=%20%5Ctt%7B30.16%20%3D%2017.56%20%2B%205x%7D%20)
Swap the sides of the equation :
⤑ ![\tt{17.56 + 5x = 30.16}](https://tex.z-dn.net/?f=%20%5Ctt%7B17.56%20%2B%205x%20%3D%2030.16%7D)
We want to remove the 17.56 first.
Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :
⤑ ![\tt{5x + 17.56 - 17.56 = 30.16 - 17.56}](https://tex.z-dn.net/?f=%20%5Ctt%7B5x%20%2B%2017.56%20-%2017.56%20%3D%2030.16%20-%2017.56%7D)
Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.
⤑ ![\tt{5x = 12.6}](https://tex.z-dn.net/?f=%20%5Ctt%7B5x%20%3D%2012.6%7D)
Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.
⤑ ![\tt{ \frac{5x}{5} = \frac{12.6}{5}}](https://tex.z-dn.net/?f=%20%5Ctt%7B%20%5Cfrac%7B5x%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B12.6%7D%7B5%7D%7D%20)
Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.
![\pink{ \boxed{ \boxed { \tt{Our \: final \: answer : \underline{ \underline{ \bold{ \tt{x = 2.52}}}}}}}}](https://tex.z-dn.net/?f=%20%5Cpink%7B%20%5Cboxed%7B%20%5Cboxed%20%7B%20%5Ctt%7BOur%20%5C%3A%20final%20%5C%3A%20answer%20%3A%20%20%5Cunderline%7B%20%5Cunderline%7B%20%5Cbold%7B%20%5Ctt%7Bx%20%3D%202.52%7D%7D%7D%7D%7D%7D%7D%7D)

Each point on the house was divided by 2.
Answer:
90
Step-by-step explanation:
The sum of squares of the deviation from mean=sum(x-xbar)²=?
x
12
6
15
9
18
12
xbar=sumx/n
xbar=(12+6+15+9+18+12)/6=72/6=12
x x-xbar (x-xbar)²
12 12-12=0 0
6 6-12=-6 36
15 15-12=3 9
9 9-12=-3 9
18 18-12=6 36
12 12-12=0 0
sum(x-xbar)²=0+36+9+9+36+0=90
So, the sum of squares of the deviations from the mean is 90.
