Lea and Rob are selling fruit for a school fundraiser. Customers can buy small boxes of orangesand large boxes of oranges. Lea s
MaRussiya [10]

The first step is to define the system of equations.

Take x and y as the cost of a small box and a large box respectively.

\begin{gathered} 2x+y=12 \\ 3x+y=16 \end{gathered}

Solve the system.

\begin{gathered} 2x+y=12 \\ y=12-2x \\ 3x+y=16 \\ y=16-3x \end{gathered}\begin{gathered} 12-2x=16-3x \\ 3x-2x=16-12 \\ x=4 \end{gathered}\begin{gathered} y=12-2x \\ y=12-2\cdot4 \\ y=12-8 \\ y=4 \end{gathered}

A small box costs $4 and a large box costs $4 too.

In a certain year, the average e-mail user sent or received 111 e-mails each day. The number of e-mails received was 3 more than
Ludmilka [50]

Answer:

Number of sent mail = 36

Number of received mail = 75

Step-by-step explanation:

Let,

x be the number of mails sent

y be the number of mails received

According to given statement;

x + y = 111      Eqn 1

y = 2x + 3     Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x + 2x + 3 = 111

3x = 111 - 3

3x = 108

Dividing both sides by 3

\frac{3x}{3}=\frac{108}{3}\\x = 36

Putting x = 36 in Eqn 2

y = 2(36) + 3

y = 72 + 3 = 75

Hence,

Number of sent mail = 36

Number of received mail = 75
