A web music store offers two versions of a popular song. The size of the standard version is 2.5 megabytes. The size of the high quality version is 4.4 mb. Yesterday, the high-quality version was downloaded twice as often as the standard version. The total size downloaded for the two versions was 2599 mb. How many downloads of the standard version were there?

10

step-by-step explanation:

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

answer

106 emergencies

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
