Answer:
7/16
Step-by-step explanation:
assume she had 8/8 units of sea shells, she then left 1/8 at home
so: 8/8-1/8=7/8
so she has 7/8 units of shells still at home
and she gives half to her friend
so: 7/8*1/2=7/16
She gave 7/16 of the original amount of shells she had to her friend
First, you would find the mean of the data. Once you have the number, you would find the difference between the mean and the other numbers. Once you have all of those numbers, you find the mean of that set. For example:
The mean of this set is 9. We then use this number to find the difference between all of the numbers. So 14-9= 5, 9-7=2, 9-6=3, 9-5=4, 13-9=4. Finding the mean of 5, 2, 3, 4, and 4 results in 18/5 or 3.6
3.6 is the mean absolute deviation.
Answer: 10
Step-by-step explanation Simplifying
2x + 7 = 3(x + -1)
Reorder the terms:
7 + 2x = 3(x + -1)
Reorder the terms:
7 + 2x = 3(-1 + x)
7 + 2x = (-1 * 3 + x * 3)
7 + 2x = (-3 + 3x)
Solving
7 + 2x = -3 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
7 + 2x + -3x = -3 + 3x + -3x
Combine like terms: 2x + -3x = -1x
7 + -1x = -3 + 3x + -3x
Combine like terms: 3x + -3x = 0
7 + -1x = -3 + 0
7 + -1x = -3
Add '-7' to each side of the equation.
7 + -7 + -1x = -3 + -7
Combine like terms: 7 + -7 = 0
0 + -1x = -3 + -7
-1x = -3 + -7
Combine like terms: -3 + -7 = -10
-1x = -10
Divide each side by '-1'.
x = 10
Simplifying
x = 10
Answer:340 or 5 depends how your using it
Step-by-step explanation:
Answer:
Rs 14257.2
Step-by-step explanation:
From the formula;
A= P(1 + i)^n
A= amount
P= principal
i= rate
n= time
A= 12000(1 + 0.09)^2
A=12000(1.09)^2
A=Rs 14257.2
