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.

Find the solution to the system of equations-2 + 2y = -4 3x + 3y = -18

AfilCa [17]

Answer:

$\boxed{x = -2~~and~~ y = -4}$

Step-by-step explanation:

-2x + 2y = -4 (times 3) -6x + 6y = -12

3x + 3y = -18 (times 2) 6x + 6y = -36

-6x + 6y = -12

<u>6x + 6y = -36 </u>+

12y = -48

$y = \frac{-48}{12}$

y = -4

Substitute the value of y to the one of equations

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

-2x - 8 = -4

-2x = -4 + 8

-2x = 4

$x = \frac{4}{-2}$

x = -2
