A volume of a cube = l × w × h = v
So 2 × 4 × 5 = 40 cm³

1 Simplify n+5+-m-3n+8n+5+−m−3n+8 to n+5-m-3n+8n+5−m−3n+8.

11-2m-(n+5-m-3n+8)11−2m−(n+5−m−3n+8)

2 Collect like terms.

11-2m-((n-3n)+(5+8)-m)11−2m−((n−3n)+(5+8)−m)

3 Simplify (n-3n)+(5+8)-m(n−3n)+(5+8)−m to -2n+13-m−2n+13−m.

11-2m-(-2n+13-m)11−2m−(−2n+13−m)

4 Remove parentheses.

11-2m+2n-13+m11−2m+2n−13+m

5 Collect like terms.

(11-13)+(-2m+m)+2n(11−13)+(−2m+m)+2n

A Web music store offers two versions of a popular song. The size of the standard Version is 2.7 megabytes (MB). The size of the
Shkiper50 [21]

Let x be number of downloads of standard version and y be number of downloads of high quality versions.

The hight quality downloads are twice as the standar downloads. So,

y=2x

The downloaded data for x standard version is 2.7x and for y high quality version is 4.2y. The total downloaded data is 3219. So,

2.7x+4.2y=3219

Substitute 2x for y in the equation and solve the obtained equation for x.

\begin{gathered} 2.7x+4.2\cdot2x=3219 \\ 2.7x+8.4x=3219 \\ x=\frac{3219}{11.1} \\ =290 \end{gathered}

So value of x is 290. Thus downloads of the standard version were 290.

Answer: 290
