You have $50 and are buying some movies on dvds that cost $15 each. write an expression that shows how much money you have left after buying m movies.

Y=50-15m

Step-by-step explanation:

since it is 15 dollars per movie we can write that as 15m. After that to find how much you have left you subtract 15m from 50, hence the equation Y=50-15m

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
