Sorry don't know explane the question
X=2
subtract 7 from both sides
Because the time moved up by 15 minutes, we would already know that it would be (blank) megabytes per 15 minutes
75 megabytes - 15 megabytes = 60
this would mean 60 megabytes are downloaded per 15 minutes
simplified by 15, our answer would be 4 megabytes downloaded per minute
both of the answers above would be acceptable :)
1/3x+3x. Hope that helps! :D
