The sum of two numbers is 140, and their difference is 20. What are the two numbers?

Answers

Answer 1

Answer:

60 and 80.

Step-by-step explanation:

If the numbers are x and y:

x + y = 140

x - y = 20     Adding:

2x = 160

x = 80

So y =  140 - 80 = 60.

Answer 2

Answer:

80 and 60

Step-by-step explanation:

Expressing the Word Problem mathematically.

Let the first number be X.

Let the second number be Y.

From the question,

[tex]x + y = 140 - - - - - (1) \\ x - y = 20 - - - - - (2) \\ From \: equation \: (2) \\ x = 20 + y - - - - - - (3) \\ Substitute \: equation \: 3 \: into \: 1 \\ 20 + y + y = 140 \\ 20 + 2y = 140 \\ 2y = 140 - 20 \\ 2y = 120 \\ Dividing \: bothsides \: by \: 2 \\ \frac{2y}{2} = \frac{120}{2} \\ y = 60 \\ Substitute \: y \: into \: quation \: 3 \\ x = 20 + 60 \\ x = 80 \\ Therefore, \: x = 80 \: and \: y = 60[/tex]

The two numbers are 80 and 60

Answers

Answer:

x = -40 and y = -64

Step-by-step explanation:

The ratio of the two numbers is 5/8, since the difference of these two numbers is 24, what is the sum

Let two numbers be x and y.

ATQ,

x-y = 24 ..(1)

and

[tex]\dfrac{x}{y}=\dfrac{5}{8}[/tex]

or

8x-5y =0 ...(2)

Multiply equation (1) by 8.

8x-8y = 192 ...(3)

Subtract equation (3) from (2).

8x-5y -(8x-8y) = 0-192

-5y+8y = -192

3y = -192

y = -64

Put the value of y in equation (1).

x-(-64) = 24

x+64 = 24

x = -64+24

x = -40

So, the values of x and y are -40 and -64 respectively.

Find the mean,median,mode, and range:5,2,5,2

Answers

Answer:

Mean = 3.5

Median = 3.5

Mode = 5, 2

Step-by-step explanation:

Hope that helps!

Mean: To find the mean, simply add the numbers together and divide by the amount of numbers in the set:

Mean: (5 + 2 + 5 + 2)/4

= (14)/4

= 3.5

Mean = 3.5

Median: To find the median, simply order from least to greatest, and find the middle number in the set. That is your median. In the case of an even amount of numbers in the set, find the mean with the two median numbers (as in this case):

Median: (2 + 5)/2

= 7/2

= 3.5

Median: 3.5

Mode: The Mode is the number that shows up the most frequently. As both given numbers show up the same amount of times (twice), there is no mode.

Mode: None.

Range: The Range is found by subtracting the greatest number with the least number:

5 - 2 = 3

Range: 3
