Dolphin= 0.433 Lion=56.3% Rabbit= 19/40 Squirrel= Tiger=65.8%

Answers

The way to line the animals is to put them in order going down. 0.433 56.3% 19/40 65.8%. Then you try to figure out what you need to convert so that you can get your answer. 56.3% changes to 0.563 because you move the decimal two places to the left. 65.8% changes to 0.658 and 19/40 is 0.475. 0.433 0.563 0.475 0.658. Now you compare each row to figure them out. When you do that your answer will be 0.433, 0.475, 0.563, and 0.658. I sleep about 9/24 of the day which is 0.375 and I will fit right befor 0.433.

In the equation 51-14x=84, what does x equal?

Answers

To solve for 'x' we need to isolate it, by getting all terms with 'x' on one side of the equation and all terms without 'x' on the other side.

To do this we can start by subtracting 51 from both sides of the equation:
51-14x-51=84-51
-14x=33

Now we need to 'move' the -14 over as well. We can do this by dividing both sides by -14:
(-14x)/(-14)=(33)/(-14)
x=(33)/(-14)

We now have 'x' isloated and out answer is there: X= -(33/14)

We can check this answer by plugging it back into the original equation:
51-14x=84
51-14(-(33)/(14))=84
51-(-33)=84
84=84 Check.
51-14x=84-->-14x=84-51-->-14x=33-->14x/-14=33/-14-->x=-33/14

Solve for x 17-x=1/3*15+6

Answers

In finding the X, please refer to the computation and explanation in this answer: 
17-X= 1/3*15+6
17-X= 11
17-11= X
6= X
So, here you get the X by solving the problem on the right first, 1/3*15 will yield 5 and 5 plus 6 will yield 11 then transfer the answer to the left and interchange it with X. So you will now have 17-11= X, and then you will get 6 as the value of X.
Solve for x
 
17 - x = 1/3*15+6

Simplify by combining like terms. 

1/3 * 15 + 6 = 5+6 = 11

11 = 17 - x
               + x

11 + x = 17
-11        -11

x = 6

Answer:  x = 6

katia makes crafts using glass jars She can buy packages of 12 jars for $9 how many jars can kitia buy with $45

Answers

Hello!

If Katia can buy packages of jars for $9, we can determine how many packages she can purchase with $45 by using the formula:

45/9 = 5

We divide the total number of money that she has by the amount of money one package of jars costs. Now, the question also asks how many jars she can buy, not just how many packages.

We know that she can buy 5 packages, and that there are 12 jars in each package. To find the total number of jars she can buy, we will multiply 5 by 12.

5 x 12 = 60

Katia can buy 60 jars with $45.

I hope this helps you! Have a lovely day!

Given that number of ants double after every ten days, form a table that shows numbe of ants from day 1 to day 91

Day                                                  Number of Ants

1                                                                       10

11                                                                      20

21                                                                     40

31                                                                     80

91                                                                    5120

Using the given values for number of ants and the number of days, you can notice the trend for values of days and number of ants.After every ten days, number of ants doubles.Using this information, you can navigate backwards up to day 1 and forward up to day 91
