With math word problem, 10 points

a web music store offers two versions of a popular song. the size of the standard version is 2.4 megabytes (mb). the size of the high-quality version is 4.2 mb. yesterday, the high-quality version was downloaded four times as often as the standard version. the total size downloaded for the two versions was 4992 mb. how many downloads of the standard version were there?

i hope this answer you! if you have any further questions or concerns, feel free to ask! : )

step-by-step explanation:

mark brainliest!

table 3 represents a direct variation function. : )

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.
