Anthony Tedesco sold his used mountain bike and accessories for $140. If he received 4 times as much money for the bike as he did for the accessories, find how much money he received for the bike. He received $for the bike.

Step-by-step explanation:

Accessories: x

Bike: 4x

Total1: 5x

Total2: 140 dollars.

x + 4x = 140 dollars

5x = 140

x = 28

Accessories: 28

Bike: 112

$112

Step-by-step explanation:

First you must see that there are 2 variables in this problem, the bike and accesories.

If the bike and accesories are equal to $140 then, x+y=140.

If the bike is 4x the amount of the accesories then 4x=y. Substitute y in the first equasion for x+4x=140.

That means 5x=140, and solving for x you get $28. Since the bike was 4x the amount of accesories then 4*28= $112.

To check your work you can solve it again. $28+$112=$140 or 28+4*28=140.

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.
