Answer:
Mean: 680.33
Median: 66
Mode: 20
Step-by-step explanation:
used a calculator ;p
The answer is B because $5.12 was removed from the total she had
(1,3) is one of the coordinates
If y is equal to 2 then you can find x by putting 2 for y so you will have:
2x + 8(2) = 20
2x + 16 = 20
2x = 20 - 16
2x = 4
x = 4/2
x=2 :)))
i hope this is helpful
have a nice day
Hence, the numbers are 16 and 4
<u>Further Explanation:</u>
First of all we have to make the equations from the word problem.
Let x be the first number and y be the second number.
Then,
The sum of two numbers is 20 => x + y = 20 => Eqn 1
The difference between three times the first number and twice the second is 40 => 3x-2y = 40 => Eqn 2
The numbers can be verified:
As the equation is verified by the values of x and y.
Hence, the numbers are 16 and 4
