Answer:

the third side is 5 2/3 in.

s - 1

Step-by-step explanation:

a = side 1

b = side 2

c = side 3

a + b + c = 15

a = b - 4 => b = a + 4

c = a + 3

a + a + 4 + a + 3 = 15

3a + 7 = 15

3a = 8

a = 8/3 = 2 2/3 in

b = a + 4 = 6 2/3 in

c = a + 3 = 5 2/3 in

The pie chart shows information about voters in a election.2800 more women vote than men.

Lyrx [107]

ANSWER

The total number of voters is
$10080$

EXPLANATION

Let the
$x$
be the number of voters that are men.

Then the women will be
$x + 2800$

The total voters will be
$x + (x + 2800)$

$2x + 2800$

We now use ratio.

We can see from the diagram that,
$130 \degree$
corresponds to men.

We can write the ratio

$x:130 \degree$

Also the total number of voters corresponds to the angle in a complete circle. This will also give us the ratio,

$(2x + 2800):360 \degree$

We can therefore write the equation,

$\frac{2x + 2800}{x} = \frac{360 \degree}{130 \degree}$

$\frac{2x + 2800}{x} = \frac{36 }{13}$

We cross multiply to get,

$13(2x + 2800) = 36x$

This implies that,

$26x + 36400 = 36x$

We group like terms to obtain,

$26x - 36x = - 36400$

This implies that,

$- 10x = - 36400$

$x = 3640$

The total number of voters
$= 2(3640) + 2800$
$= 10080$

The total number of voters is
$10080$

Answer:

Linear function

<h3> $y = \frac{x}{2} - 5$ </h3>

Step-by-step explanation:

<h2> $y = \frac{x}{2} - 5$ </h2><h3>Linear function</h3>

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1.

<h2> $y = \frac{2}{x} + 3$ </h2><h3>Not linear function</h3>

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1

, the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.

<h2> $y = {2}^{x} - 1$ </h2><h3>Not linear function</h3>

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.

<h2> $y = {x}^{2} + 7$ </h2><h3>Not linear function</h3>

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 2.

<h3>Hope it is helpful...</h3>
