Alexis has a rectangular piece of red paper that is 4 centimeters wide. it's length is twice it's width. she glues a rectangular

Sergio039 [100]

The area of the red piece of paper is A= 4(2*4)= 4*8= 32 in^2.
The area of the blue piece of paper is A= 3*7=21 in^2. You subtract 21 from 32 and the difference is 11. So 11in^2 is visible.

Solve the proportion. I need to show much work so a step by step explanation would help!

kkurt [141]

Answer:

Solution: x=5

Step-by-step explanation:

Equations

This is an equation in the form of a proportion or ratio:

$\displaystyle \frac{2}{x+3}=\frac{5}{4x}$

To solve it, we eliminate the denominators by multiplying by both of them.

Multiply by (x+3)(4x):

$\displaystyle (x+3)(4x)\frac{2}{x+3}=(x+3)(4x)\frac{5}{4x}$

Simplify both sides:

$(4x)*2=(x+3)*5$

Operate:

$8x=5x+15$

Simplify:

$3x=15$

Solve for x:

$x=15/3=5$

Solution: x=5

sergejj [24]

Answer:

First, let's make an expression!

If you meant a different equation..sorry

$\frac{8+6}{7-3} +\frac{1}{2}$

Hope this is what you meant!

$\frac{14}{4} +\frac{1}{2}\\\frac{7}{2} +\frac{1}{2} \\\frac{8}{2} =4$

Hope this helps!

P.S. Stay Safe!
