Answer:
x=-1/4
Step-by-step explanation:
2/5+3/5x=x+5/10
subtract 2/5 form both sides
3/5x=x+1/10
subtract x form both sides
-2/5x=1/10
Multiply both sides by 5
-2x=1/2
x= - 1/4
Answer:
Account balance is not proportional to the number of weeks.
Step-by-step explanation:
Initially Adrian's saving account balance was = $28
He deposits $15 in his account each week.
If we denote week with a variable 'x' then after 'x' weeks total amount in is account = $15x
So, total amount in his account after 'x' week will be;
y = 15x + 28
It's a linear equation representing total amount after 'x' weeks with a constant growth rate of 15 and initial amount 28.
In other words equation is in the form of y = mx +b.
This equation doesn't show the proportional relation because equation in the form of y = kx represents the relation of proportionality only.
Answer: 31.42 inches.
Step-by-step explanation:
Since the circumference of a circle equation is C = πd (also C = 2πr, in which 2*r = d), you can just substitute d = 10.
Then you get C = π*10 ≈ 31.42 inches.
Answer:
The answer is "Please find the given plot which is shown in the figure".
Step-by-step explanation:
![Minimum = 11\\\\Lower \ quartile = Q_1 = 12\\\\Median = Q_2 = 23.5\\\\Upper \ quartile = Q_3 = 27\\](https://tex.z-dn.net/?f=Minimum%20%3D%2011%5C%5C%5C%5CLower%20%5C%20quartile%20%3D%20Q_1%20%3D%2012%5C%5C%5C%5CMedian%20%3D%20Q_2%20%3D%2023.5%5C%5C%5C%5CUpper%20%5C%20quartile%20%3D%20Q_3%20%3D%2027%5C%5C)
Boxes are between 12 and 27
The box divides a line at 23.5 ![\to Q2](https://tex.z-dn.net/?f=%5Cto%20Q2)
The left whisker would be 11-12 ![\to Minimum \ \ to\ Q_1](https://tex.z-dn.net/?f=%5Cto%20Minimum%20%5C%20%5C%20to%5C%20%20Q_1)
The proper whisker will be 27 to 33
Answer: 8-5r
