Solve for w.<br> 2w=12-4w<br> Simplify your answer as much as possible.

aev [14]

So we have an equation:
2w=12-4w
Firstly, let's simplify, and divide all terms by 2:
w=6-2w
Now, we add 2w over to the other side:
3w=6
And finally, we divide both sides by 3:
w=2
Hope this helps!

Draw an area model that demonstrates that the quotient of 2080 and 40 is 52.

Scrat [10]

Area model is used to illustrate multiplication and division operations.

See attachment for the area model

The equation can be represented as:

$\frac{2080}{40} = 52$

Express 2080 as 1200 + 800 + 80

$\frac{1200 + 800 + 80}{40}=52$

Express as

$\frac{1200 + 800 + 80}{40}=\frac{1200}{40} + \frac{800}{40} + \frac{80}{40}$

Divide

$\frac{1200 + 800 + 80}{40}= 30 + 20 + 2$

The ratio of the length of a rectangular floor to its width is 3:2. If the length of the floor is 12 meters, what is the perimet

atroni [7]

Hi!

<h3>Let's set up a proportion and cross multiply to solve. </h3>

$\frac{3}{2} \frac{12}{w}$

<h3>Solve for w</h3>

2 * 12 = 24

24/3 = 8

<h3>To find the perimeter of the floor, use this equation</h3>

<em>(l = length</em>

<em>w = width </em>

<em>p = perimeter)</em>

l + l + w + w = p

<h2>The perimeter of the floor is 40 meters. </h2>

Hope this helps! :)
