The sum of two numbers is 87. the difference of two numbers is 65 what are the two numbers

Step-by-step explanation:

Let the two numbers be x and y

By the question

x + y = 87 equation (I)

x - y = 65 equation (II)

Now adding both equations we get

2x = 152

x = 152 / 2

Therefore x = 76

Putting x = 76 in equation i

76 + y = 87

y = 87 - 76

Therefore y = 11

The two numbers are 76 and 11.

Hope it helps :)

11, 76

Step-by-step explanation:

Let the two numbers be x and y.

According to the given conditions:

x + y = 87(1)

x - y = 65(2)

Adding equations (1) & (2)

x + y = 87

x - y = 65

2x = 152

x = 152/2

x = 76

Plug x = 76 in equation (1)

76 + y = 87

y = 87 - 76

y = 11

Thus the two numbers are 11 and 76.

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
