18-7x=35 should be the answer and if you subtract 18 from 35 you would get 17. then you have -7x=17. x=17/-7

Elle and heather drew floor models of there living rooms.Elles model respresented 20 feet by 15 feet.Heathers model respresented

ludmilkaskok [199]

Answer:

Heather's model represents the greater area.
$24\ ft^2$ greater.

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

$A=lw$

Where "l" is the lenght of the rectangle and "w" is the width.

The formula for calculate the area of a square is:

$A=s^2$

Where "s" is the side lenght.

In this case, knowing that Elle's model represented 20 feet by 15 feet, we can say that:

$l=20\ ft\\w=15\ ft$

Therefore, substituting these values into the formula $A=lw$ , we get that the area is:

$A_1=(20ft)(15ft)=300\ ft^2$

Since Heather's model represented 18 ft by 18 feet, we can identify that:

$s=18ft$

Substituting this value into $A=s^2$ , we get this area:

$A_2=(18ft)^2=324\ ft^2$

Notice that Heather's model represents the greater area.

To calculate how much greater it is, subtract the areas. Then:

$324\ ft^2-300\ ft^2=24\ ft^2$

The slope of the graphed line is. Which formulas represent the line that is graphed? Check all that apply. Y – 1 = (x – 2) y – 2

IceJOKER [234]

The formula or equation which represent the graphed line with point (1,2) (4,4) and slope 2/3 are,

$(y-2)=\dfrac{2}{3}(x-1)\\$

$(y-4)=\dfrac{2}{3}(x-4)\\$

<h3>What is the equation of a graphed line?</h3>

The equation of a graphed line is a way to represent the line which lies on a point on the xy-coordinated with and informed about the steepness and the direction of the line.

The standard form of the equation of a graphed line can be given as,

$y=mx+c$

Here, (<em>c</em>) is the y intercept of the line and (<em>m</em>) is the slope of the line.

Here, the slope of the graphed line is 2/3. The graph for this problem is attached below.

The two point in the graph below are (1,2) and (4,4). Then the equation of the line, for this two points with slope 2/3 can be given as,

$(y-2)=\dfrac{2}{3}(x-1)\\$

Using the points (4,4), we get,

$(y-4)=\dfrac{2}{3}(x-4)\\$

Thus, the formula or equation which represent the graphed line with point (1,2) (4,4) and slope 2/3 are,

$(y-2)=\dfrac{2}{3}(x-1)\\$

$(y-4)=\dfrac{2}{3}(x-4)\\$

You roll a 6-sided die. Find the P(4).

ludmilkaskok [199]

Because all outcomes are equally weighted, the probability you are looking for is given by :-
Number of favorable eventsTotal number of events
Number of favorable events
Total number of events

In your case: 6 or Even outcome={2,4,6}
6
or Even outcome
=
{
2
,
4
,
6
}
and Outcomes={1,2,3,4,5,6}
Outcomes
=
{
1
,
2
,
3
,
4
,
5
,
6
}

Hence:

Number of favourable eventsTotal number of events=36=12

Endpoint P(5, -3) and Q(2,4)

NikAS [45]

The midpoint of these two points would be (3.5, 0.5)

In order to find this, you need to take the average of the two point that you have. To do that, add the numbers together and divide by 2. Start with just the x values.

(5 + 2)/2 = 3.5

Now the y values

(-3 + 4)/2 = 0.5

This gives us the ordered pair of (3.5, 0.5)
