Ruben brought 2 large popcorn buckets and 4 small drins for 20. Lucia bought 2 large popcorn buckets and 2 small drinks for 14.What was the cost of the large popcorn and the small drinks

Cost of large popcorn = 4

Cost of small drinks = 3

Step-by-step explanation:

Given that :

Let cost of large popcorn = x

Cost of small drinks = y

Cost of 2 large popcorn and 4 small drinks

2x + 4y = 20

2x + 2y = 14

x + 2y = 10 - - - (1)

x + y = 7 - - - (2)

Subtract :

2y - y = 10 - 7

y = 3

Substitute y = 3 into (2)

x + 3 = 7

x = 7 - 3

x = 4

Hence,

Cost of large popcorn = 4

Cost of small drinks = 3

they are simplified

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.
