The dance committee of pine bluff middle school earns $72 from a bake sale and will earn $4 for each ticket they sell for the spring fling dance. The dance will cost $400. write an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this years dance.

The correct answer is 4 × x + 72 > 400.

Step-by-step explanation:

The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance.

The dance will cost $400.

Let x number of tickets the committee could sell.

Total money earned by the committee is 4 × x + 72.

The committee should have some left over money after spending for the spring fling dance which costs $400.

Thus the inequality to determine the number of tickets the committee needs to sell to have money left over after they pay for this year's dance is given by,

4 × x + 72 > 400.

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.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
