If D is the midpoint of EG, find the length of EG
Brrunno [24]

ED = x - 5 <em>given</em>

DG = 4x - 38 <em>given</em>

ED = DG <em>definition of midpoint</em>

x - 5 = 4x - 38 <em>substitution</em>

-5 = 3x - 38 <em>subtraction property of equality (subtracted x from both sides)</em>

33 = 3x <em>addition property of equality (added 38 to both sides)</em>

11 = x <em>division property of equality (divided 3 from both sides)</em>

ED = x - 5 → ED = 11 - 5 → ED = 6 <em>substitution</em>

since ED = DG, then DG = 6 <em>transitive property</em>

ED + DG = EG <em>segment addition property</em>

6 + 6 = EG <em>substitution</em>

12 = EG <em>simplified like terms</em>

Answer: 12

If it requires 6 pounds of wild caught animals to create 1 pound of salmon, what percent of the wild caught animals are wasted?
Oduvanchick [21]

The percentage of animal wasted is the number of animal wasted over 100

85.7%  of the wild caught animals are wasted

<h3>How to calculate the animal wasted</h3>

From the question, we have:

Animals caught = 6 pounds

Salmon = 1 pound

The total weight in the system is:

Total = 6 pounds + 1 pound

So, we have:

Total = 7 pounds

The percent of wild caught animals wasted is then calculated as:

\%Wasted = \frac{6}{7} * 100\%

Simplify

\%Wasted = 85.7\%

Hence, 85.7%  of the wild caught animals are wasted

The are of a rectangle is 5/8 square feet. The width of the rectangle is 2 1/2 feet. What is the length of the rectangle?
bezimeni [28]
The length of the rectangle is 0.25 or 1/4. This is because the area is equal to 5/8 or 0.625, and the width of the rectangle is 2 1/2 or 0.25. So 0.625/2.5 = 0.25 or 1/4.

2 and 1/4 = 9/4

4 and 1/12 = 49/12

3 and 2/3 = 11/3

Perimeter = 9/4 + 49/12 + 11/3

= 27/12 + 49/12 + 44/3

= 120/12

= 10inches
