Answer:

Our actual answer is 1/18 greater than our estimate

1/2 < 5/9

Step-by-step explanation:

5/8 is close to 1/2

8/9 is close to 1

1/2 * 1 = 1/2

Our estimate is 1/2

Actual answer

5/8 *8/9

Rewriting

5/9 * 8/8

5/9

How close

5/9 - 1/2

Getting a common denominator

5/9*2/2 - 1/8 *9/9

10/18 - 9/18

1/18

Our actual answer is 1/18 greater than our estimate

Hey There!

Here is your answer:

First write the equation down:

-3 4/5 ÷ -3 1/6

Then put the mixed fractions into whole numbers:

-3 4/5= 5×-3=-15+4=-11= -11/5
&
-3 1/6= 6×-3=-18+1=-17= -17/6

Now right the new problem:

-11/5×6/-17

Now multiply:

-11×6=-66
5×-17=-85

Which means -66/-85 is your answer!

Hope this helps!

Find the missing terms of the sequence and determine if the sequence is arithmetic, geometric, or neither.
Minchanka [31]

Answer:

33,11,−11,−33,<u>-55,-77.</u>

Step-by-step explanation:

For an AP a_1,a_2,a_3,....,a_n.

a_2-a_1=a_3-a_2

In this given AP,

11-33=-11-11\\\\-22=-22=d

It means the given sequence is an AP.

First term, a = 33

d = -22

Fifth term :

a_5=a+(n-1)d\\\\a_5=33+(5-1)\times (-22)\\\\a_5=-55

Sixth term :

a_6=a+(n-1)d\\\\a_6=33+(6-1)\times (-22)\\\\a_6=-77

So, the sequence is 33,11,−11,−33,<u>-55,-77.</u>
