Length: 2x + 4
Width: x

Make 2(length) + 2(width) add up to 26 in an equation.

2(2x + 4) + 2(x) = 26

Distribute 2 inside the parentheses.

4x + 8 + 2x = 26

Combine like terms.

6x + 8 = 26

Subtract 8 from both sides.

6x = 18

Divide both sides by 6.

x = 3

Plug 3 for x into the length and width.

Length: 2(3) + 4 = 10 m

Width: (3) = 3 m

Use a common denominator to determine whether the ratios form a proportion.

Marysya12 [62]

Well, the common denominator of6 and 15 would be three so you would get 2 and 3

the common denominator of 30 and 80 would be 10 and it would equal 3 and 8

Help i’m begging plsss

olga_2 [115]

Answer:

$x=8$

Step-by-step explanation:

Given

$AB||CD$

$\angle ABC = 5x + 50$

$\angle BCD = 7x + 34$

Required

Find x

If $AB||CD$ i.e. If AB is parallel to CD, then

$\angle ABC = \angle BCD$

Substitute values for ABC and BCD

$5x + 50 = 7x + 34$

Collect Like Terms

$5x - 7x = -50 + 34$

$-2x = -16$

Multiply through by $-\frac{1}{2}$

$-\frac{1}{2} * -2x = -16 * -\frac{1}{2}$

$\frac{1}{2} * 2x = 16 * \frac{1}{2}$

$\frac{2x}{2} = \frac{16}{2}$

$x = \frac{16}{2}$

$x=8$

What is the approximate percent decrease when a fish count goes down from 850 to 500? The percent decrease is approximately 40%.

Korolek [52]

Answer:

<h2><em>The percent decrease is approximately 40%. </em></h2>

Step-by-step explanation:

Step one:

given data

initial count of fish= 850

final count of fish= 500

Required

% decrease

Step two:

% decrease= final-initial/initial*100

substitute

% decrease= 850-500/850*100

% decrease=350/850*100

% decrease= 0.41*100

% decrease= 40.1%

<em>The percent decrease is approximately 40%. </em>
