Answer:

-6n + 8

Step-by-step explanation:

(-8n + 11) + (2n - 3)

First let's look at the expressions within the parentheses.

-8n + 11 ⇒ This expression is fully simplified because you cannot add different variables together.

2n - 3 ⇒ This expression is fully simplified because you cannot subtract different variables together.

Since we are adding these expressions, we can take away the parentheses.

-8n + 11 + 2n - 3

Now, let's rearrange the term so the like terms are next to each other.

-8n + 2n + 11 - 3

Simplify the variable.

-6n + 11 - 3

Simplify the constants.

-6n + 8

This is your simplified expression.

Hope this helps!

It was recently estimated that females outnumber males by about three or two. If there are 1770 people in a county, how many of

max2010maxim [7]

GIVEN

1) Females outnumber males by 3 to 2.

2) There are 1770 people in the city.

SOLUTION

Let the number of males be x and the number of females y. Therefore, the total number of people can be written to be:

$x+y=1770\text{ -----------(1)}$

If there are 3 females for every 2 males, we have that:

$\begin{gathered} \frac{y}{3}=\frac{x}{2} \\ \therefore \\ x=\frac{2y}{3}\text{ ----------(2)} \end{gathered}$

We can substitute equation (2) into equation (1) and solve for y:

$\begin{gathered} \frac{2}{3}y+y=1770 \\ \frac{2y+3y}{3}=1770 \\ 5y=1770\times3 \\ 5y=5310 \end{gathered}$

Dividing both sides by 5, we have

$y=1062$

There are 1062 females in the county.

Which inequality is shown in this graph

Katena32 [7]

ANSWER

$y \leqslant - 2x - 2$

EXPLANATION

The boundary line passes through (-2,2) and (0,-2).

The slope of this line is

$m = \frac{ - 2 - 2}{0 - - 2}$

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

The y-intercept is , c=-2.

The slope-intercept form of this line is given by;

$y = mx + c$

We substitute values to obtain;

$y = - 2x - 2$

Since the lower half-plane is shaded the required inequality is

$y \leqslant - 2x - 2$
