A Web music store offers two versions of a popular song. The size of the standard version is 2.9 megabytes (MB). The size of the
GrogVix [38]

s +h = 1070 ( total number of downloads)

Rewrite as s =1070 - h

2.9s + 4.4h = 4393 ( total download size)

Substitute:

2.9(1070-h) + 4.4h = 4393

Simplify:

3103 - 2.9h + 4.4h = 4393

Combine like terms:

3103 + 1.5h = 4393

Subtract 3103 from each side:

1.5h = 1290

Divide both sides by 1.5:

h = 1290 / 1.5

h = 860

Replace h with 860 in first equation to solve for s:

s + 860 = 1070

s = 1070 - 860

s = 210

There were 210 standard downloads and 860 high quality downloads

C)<br> A bus drives for 3/2 hours at an average speed of 56 mph.<br> How far does the bus drive?
natta225 [31]

Answer:

The bus drives 84 miles

Step-by-step explanation:

The question relates to relationship between average speed and time

The given parameters are;

The time duration in which the bus drives = 3/2 hours = 1.5 hours

The average speed of the bus = 56 mph

The formula average speed is given as follows;

Average \ speed = \dfrac{The \ total \ distance \ driven}{The \ time \ duration \ of \ travel}

Therefore, we have;

The total distance driven = Average speed × The time duration of travel

The total distance driven = The distance the bus drives

Substituting the given values, gives;

The distance the bus drives = 56 miles/hour × 1.5 hours = 84 miles

The distance the bus drives = 84 miles.
