How do you convert 7(x-4)=14 into a word problem

UkoKoshka [18]

Answer:

$7(x - 4) = 14 \\ 7x - 21 = 14 \\ 7x = 14 + 21 \\ 7x = 35 \\ \frac{7x}{7} = \frac{35}{7} \\ x = 5$

I need help with this pls be nice and tell me the answer :)

KIM [24]

Answer:

m=-10

Step-by-step explanation:

just to make this easier ill subtract 2 from each side to get

2/3m = 1/6m -5

now multiply each side by 6 to get rid of denominators (this just makes it easier)

now in the next steps we simplify

4m = 1m -30

3m= -30

m=-10

Find the value of r so the line that passes through (-5,2) and (3,r) has a slope of -1/2

soldier1979 [14.2K]

The value of r so the line that passes through (-5,2) and (3,r) has a slope of -1/2 is -2

<u>Solution:</u>

Given that line is passing through point (-5, 2) and (3, r)

Slope of the line is $\frac{-1}{2}$

Need to determine value of r.

Slope of a line passing through point $\left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right)$ is given by following formula:

$\text { Slope } m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ --- eqn 1

$\text { In our case } x_{1}=-5, y_{1}=2, x_{2}=3, y_{2}=\mathrm{r} \text { and } m=-\frac{1}{2}$

On substituting the given value in (1) we get

$\begin{array}{l}{-\frac{1}{2}=\frac{r-2}{3-(-5)}} \\\\ {\text { Solving the above expression to get value of } r} \\\\ {=>-\frac{1}{2}=\frac{r-2}{3+5}} \\\\ {=>-8=\frac{r-2}{3+5}} \\\\ {=>-8=2(r-2)} \\\\ {=>-8=2 r-4} \\\\ {=>2 r=-8+4} \\\\ {=>2 r=-4} \\\\ {=>r=\frac{-4}{2}=-2}\end{array}$

Hence the value of "r" is -2

A floor plan of 's cheryl´s bedroom and closet is shown. The height of the bedroom is 7 feet. The height of the closet is 6 fee

mylen [45]

Answer:

The total volume of the bedroom and closet is 42 feet or sq2

No, it doesn't make sense to find the bedroom floor and closet floor area combined because this is abt the height and volume, not the flooring plan (area)

Step-by-step explanation:

You multiple 7*6 to get the 42 answer
