Mr. O'leary works as a cook at a pizzeria. Yesterday, he prepared 6 pizzas in 10 minutes. Today, he prepared 15 pizzas in 25 minutes.
Does the scenario represent a direct variation? Explain your reasoning.

Ahas the coordinates (–4, 3) and b has the coordinates (4, 4). if do,1/2(x, y) is a dilation of △abc, what is true about the image △a'b'c'? check all that apply. ab is parallel to a'b'. do,1/2(x, y) = the distance from a' to the origin is half the distance from a to the origin. the vertices of the image are farther from the origin than those of the pre-image. a'b' is greater than ab.

If 1 is divided by the sum of y& 4. the result is equal to 3 divided by 4 .find the value of m?

Lee has $1.75 in dimes and nickels. the number of nickels is 11 more than the number of dimes. how many of each coin does he have?
