Do you know how to simplify, let's say for example,    x⁵/x²  ?

When the bases are the same, you can just subtract the exponent in
the denominator from the exponent in the numerator.  So  x⁵/x² = x³ .

Now look at  x⁷/x⁷ .  From that same handy tip, x⁷/x⁷ = x⁰ .

BUT ... any fraction with the same number on top and bottom
is equal to ' 1 '.  So  x⁰ = 1 , no matter what 'x' happens to be.

Does that do anything for you ?

1 pint is equal to 16 ounces. 
You need to know how many pints in 445 ounces. 

1 pint            x pints
-------------- = ----------------
16 ounces     445 ounces

You can cross multiply. 
1*445 = 16x
445 = 16x

Divide by 16 on both sides. 
27.8125

27.8125 pints

Is 1/2 greater than 1/3

Answers


To find whether 1/2 is greater than 1/3, it is important to convert them to decimals. By converting them to decimals, we can visually understand the number that is greater.
1/2 = 0.5
1/3 = 0.33
So from the above deduction we can conclude that 1/2 is greater than 1/3. I hope the procedure is not that complicated for you to understand. You can always use this procedure for finding the answer to similar kind of questions in future without requiring any help from anyone else.
Obviously 1/2 = 0.5 and 1/3 = 0.33 , so what we need to know is which is bigger , 0.5 or 0.33 ,in this case most would think that 0.33 is bigger than 0.5 because its 5 and 33.
 
Example : if you imaged having apples , wouldn't you want 1 apple out of 2 instead of 1 apple out of 3? yes.We just converted the fractions from 1/2 to 0.5 and 1/3 to 0.33.

Now why would 0.5 also known as 1/2 be greater than 0.33 also known as 1/3, is it because its closer to an whole number? or is 0.33 greater because 33 is simply bigger than 5. Yeah that's what most people think , and that's where they go wrong.

If you look back at the apple example you will have your answer.

 now that you looked back at it this means the answer is yes 1/2 is greater than 1/3 

the bill for a pizza was 14.50 . Charles paid for 3/5 of the bill. Show two ways to find how much he paid

Answers

Charles paid $8.70 of the bill.

The first way we can find this is:

= Proportion that Charles paid for x Cost of pizza

= 3/5 x 14.50

= 43.5 / 5

= $8.70

The second way is:

= Cost of Pizza - Proportion that others paid for

= 14.50 - ( (1 - 3/5) x 14.50)

= 14.50 - ( 2/5 x 14.50)

= 14.50 - 5.80

= $8.70

In conclusion, Charles paid $8.70 out of the total bill for the pizza.

Find out more at brainly.com/question/18773038.
Well, if the pizza total was $14.50 and if there were 5 people in total, you'd do 14.50 divided by 5 to get $2.09 per person. If Charles paid 3/5 then do 2.09 times 3 to get $6.27.

5x-5=12
please solve the equation​

Answers

Answer:

x=3.4

Step-by-step explanation:

Move all the terms that don't contain X, to the right side and then solve for X.

Answer

x = 17/5= 3.4

Step-by-step explanation:

5x - 5 = 12

5x= 12+5  (move -5 to other side of equation it becomes +5)

5x= 17 (add 5 to 12)

5x/5 = 17/5   (divide whole equation by 5)

x= 17/5= 3.4

Which one of these numbers isn't like the others?:21, 15, 6, 16, 27

Answers

If you want to know which one of the following numbers 21, 15, 6, 16, 27 isn't like the others, you can see it here:

21 / 3 = 7
15 / 3 = 5
6 / 3 = 2
16 ... you can't divide 16 by 3
27 / 3 = 9

So, the result would be 16.
16 because it isnt divisible by 3 like all the other numbers
