First, let’s start off by removing the two that don’t a a brother or sister. That leaves 10 people who do. The we calculate the access answers. They go in the middle. It’s 6. Then we have one more that has only a sister, put that at the S side. Then we have 3 more left that have only a brother, put them on the B side. Then you have 10 dots on the diagram for the 10 peoples that have a brother and/or a sister.

To conclude:
3 on B
6 in between
1 on S

The cost (c) to hire a dog trainer is varies directly with the amount of time (h) in hours spent training the dog.

NNADVOKAT [17]

Answer:

Part A) The proportional equation is $c=55h$

Part B) 8 hours of training

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

Let

c -----> the cost to hire a dog

h ----> the amount of time in hours

The linear equation is equal to

$c=kh$

Sue spent $660 on 12 hours of obedience training for her dog Muffin

Find the value of k (constant of proportionality)

$k=y/x$

substitute the values

$k=660/12=55$

therefore

The linear equation is

$c=55h$

For $c=\$440$

Find the value of h

substitute in the equation and solve for h

$440=55h$

$h=440/55=8\ hours$

Look at the figure find the value of x for which l || m

Orlov [11]

Answer:

x=5

Step-by-step explanation:

19x and its vertical angle are equal. Lets call that angle y

<y and 17x are same side interior angles. Same side interior angles add to 180 if the lines are parallel. Since l is parallel to m.

<y + 17x=180

We know that y and 19x are equal since they are vertical angles, so we can substitute this in.

19x+ 17x = 180

Combine like terms.

36x = 180

Divide each side by 36

36x/36 = 180/36

x = 5

6 equals 1 minus 2n plus 5

fomenos

6=1-2n+5
Above is the equation.
Combine like terms
6=-2n+6
Subtract 6 from both sides
0=-2n
Divide by -2
0=n

Hope this helped!<span />
