(30 2/3 *2)+(25 1/2*2)= 61 1/3+ 51=112 1/3 yards. The answer is b
Answer:
The ordered pair solutions are:
C. (1,-3)
E. (2,5)
Step-by-step explanation:
Given inequality:

To check from the list of ordered pairs which are the solution of the inequality.
Solution:
In order to check for the solutions to the inequality, we will plugin the ordered pairs in the inequality and check if it holds true. Each ordered pair is in the form
.
Plugging in each ordered pair in the given inequality to find the solutions.
<em>A) (-3,-2)</em>



The above statement can never be true and hence it is not a solution.
<em>B) (3,14)</em>



The above statement can never be true and hence it is not a solution.
<em>C) (1,-3)</em>



<u>The above statement is always true and hence it is a solution.</u>
<em>D) (1,6)</em>



The above statement can never be true and hence it is not a solution.
<em>C) (2,5)</em>



<u>The above statement is always true and hence it is a solution.</u>
Lucía needs 13.33 feet of cotton.
Since Lucía makes braided key chains out of cotton cord, and for every 8 feet of cotton cord she has, she can make 3 braided key chains, to represent the relationship between the feet of cotton cord and the number of key chains and find the number of feet of cotton cord Lucia needs to make 5 key chains, the following calculations must be performed, through a cross multiplication:
- 8CC = 3KC
- 3 = 8
- 5 = X
- 5 x 8/3 = X
- 40/3 = X
- 13.33 = X
Therefore, Lucía needs 13.33 feet of cotton.
