A toolbox contains a pile of mixed up pile of wrenches. The wrenches are all labeled with the dimension of their openings in fra

1.

     a)Two different methods for ordering these wrenches are either
     converting the measurements into decimal or converting them into
     fractions. 

     b) I chose to convert them into fractions with an LCD of 16. The fractions
     are: 8/16, 12/16, 6/16, 10/16, 5/16, 7/16, 11/16

     c) The ordered form of the fractions, from least to greatest, is 5/16, 3/8,
     7/16, 1/2, 5/8, 11/16, 3/4

2. I don't see how I can put them on a number line. 

3. The number line can definitely be used to support the answer from part C (if it is done correctly). That is because if the order on the number line is the same as the order in C, then we know that C is correct. In addition, since the number line includes benchmarks, we can easily see if the answer to C is incorrect.

For some reason, the value of "w" is not supplemented into the equation, which is weird, but whatever. I will answer the problem for you.

The answer you are looking for is -5.

Solution/Explanation:

Writing out the expression first

-7/3x+y²

Substituting the given values of the variables, only "x" and "y"

-7/3(6)+(-3)²

Simplifying

(-7/3)(6)=-14

(-3)²=9

So, we will come up with -14+9.

This simplifies to -5.

So, therefore, the final answer to this problem is -5.

Hope this helped answer your question for you. Good day to you.

There are 4 empty seats and 76 occupied seats in a train. What percentage of the seats on the train are empty?
Norma-Jean [14]

Answer:

5%

Step-by-step explanation:

fraction empty = empty / total

                                = 4/ (76+4)

                                 = 4/80

                                  =1/20

Changing to a percent

1/2 *5/5 = 5/100 = 5%
