Alan is 14 years old
He is twice as old as James
then Alan is the elder brother
Alan is twice as old means his age is double the age of James
Alans age = 2 x james age
that means James must be half of Alans age
Alans age = 14 years
James age = 14 / 2 = 7 years
therefore James is 7 years old
Answer is C. usual balance
Answer:
The solution of the system of equations is the point 
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Multiply the equation B by 2 both sides
------> equation C
Adds equation A and equation C
Find the value of y
Substitute the value of x in equation A
The solution of the system of equations is the point
Answer:
the answer is c
Step-by-step explanation:
you have to multiply the f xn and then add 7 that's when you get n and when you get that you have to find n which means you minus n-f and you get 46
<u><em>Step-by-step explanation:</em></u>
<u><em>Below are an example using the data values</em></u>
<u><em>{ 11 , 10 , 17 , 18 }</em></u>
<em><u>Step 1: What is MAD?</u></em>
MAD is the average distance between each data value. <MAD> is used to see variation of the data. The larger the MAD, the further apart the numbers are.(and vice versa)
<em><u>Step 2: Find the mean</u></em>
11 + 10 + 17 + 18 = 56
56/4 = 14
<u><em>Step 3: Formula to find the Absolute Deviations or distance of the data value to the mean</em></u>
Find the absolute value of the difference between each data value and the mean: | data value – mean | or I mean - data value I
<u><em>Step 4: Find the Absolute Deviations</em></u>
14 - 11 = 3
14 - 10 = 4
17 - 14 = 3
18 - 14 = 4
<em><u>Step 5: FInd the mean of the Absolute Deviations or MAD</u></em>
3 + 4 + 3 + 4= 14
14/4 = 3.5
