13-5m=4-6m show work please

1 answer:

4 0

First subtract 4 from both sides
$13 - 4 - 5m = - 6m$

then simplify
$9 - 5m = - 6m$

add -5 to both sides
$9 = - m$

since a variable shouldn't be negative the answer should be
$m = - 9$

(I prefer having the variable on the left side)

the perimeter of a standard-sized rectangular rug is 84 ft the length is 22 ft longer than the width find the dimensions

sergij07 [2.7K]

Answer:

The length would be 32 and the width would be 10

Step-by-step explanation:

For the purpose of this, we'll set the width as x. We can then define the length as x + 22 since we know it is 22 ft longer than the width. Now we can use those along with the perimeter formula to solve for the width.

P = 2l + 2w

84 = 2(x + 22) + 2(x)

84 = 2x + 44 + 2x

84 = 4x + 44

40 = 4x

10 = x

Now since we know that the width is 10ft, we can add 22ft to it to get the length, which would be 32ft.

Find the slope(6,8) and (9,10)

USPshnik [31]

name the points

a=(x1,y1) b=(x2,y2)

a=(6,8) b=(9,10)

use the slope formula

$m=\frac{y2-y1}{x2-x1}$

replace

$\begin{gathered} m=\frac{10-8}{9-6} \\ m=\frac{2}{3} \end{gathered}$

answer= The slope is equal to 2/3

a=(9,10) b=(6,8)

using the formula

$\begin{gathered} m=\frac{y2-y1}{x2-x1} \\ m=\frac{8-10}{6-9} \\ m=\frac{-2}{-3}=\frac{2}{3} \end{gathered}$

slope will also be 2/3
