Answer:
8 and 4
Step-by-step explanation:
You find half of the sum and subtract half of the differece for 6 and the other 6 you add the hal of the difference.
When adding fractions, you only add the numerator if the denominators are the same.
In this case, the answer would be:

or

Which when simplified is:
Answer: 64
Step-by-step explanation:
64 is because 4*4*4 is 64 and 8*8 is 64
Answer:
$13
Step-by-step explanation:
8x1=$8 next 4x2=$8 than $8-$3=$5 into $8+$5=$13
Where .75 will be on a number line always varies depending on how far out your number line goes. the decimal .75 is also known as 3/4, so the easiest way to find out where 3/4 is on a number line is to divide you number line into 4 even sections. this can be difficult if you have an odd number,, but it will always work as long as you divide the length of your number line by 4 to find out where to make your even sections. below is an example on how this would work:
lets say this is your number line
-------------------------
that number line contains 24 dashes,, so if you take that number (which is the length of the number line) and divide it by 4 you will find where 3/4 is.
24 ÷ 4 = 6
this means that at every 6,, you add 1/4. on the number line it would look like the following:
------I------I------I------
1/4 2/4 3/4
this technique shows you where 3/4/0.75 is on your number line.
