What are 3 complex fractions that simplify to 1/4??
Aleksandr-060686 [28]
<span>Give 3 complex fractions that simplify to ¼
Complex fractions are bigger fractions that can be simplified into smaller fractions.</span> <span>=> First is 15 / 60
     15/60 = 1 /4
=> second is 50/200
50/200 = 1 / 4
=> Third is 43/172
43/172 = 1 / 4

There are many possible answer. There are infinite complex fractions that can be simplified to 1 /4. I only gave 3 examples to show how simplified fraction works.</span>

What is he total coast to print exactly 15 copies?
artcher [175]

You would start by finding out how much 10 and 20 cost per copy

10: 40-25 = 15/10 = $1.50 dollars per copy

20 (This is for checking your math, not required): 55-25 = 30/20 = $1.50 dollars per copy

So, to find 15 copies you would use this formula: 25 + 1.5x

25 + 1.5(15)

25 + 22.5

$47.50 for 15 copies

Now for the second question:

160 - 25 = 135/1.5 = 90 copies

90 copies for $160

the absolute value of the sum of two different integers with the same sign is 8. Pat says there are three pairs of integers that
Irina18 [472]
Disagree
They say there are three pairs of integers that match, well..
1+7=8
2+6=8
3+5=8

-1+-7=-8
-2+-6=-8
-3+-5=-8
The same applies to negative integers because the absolute value of -3 and 3 is still 3. No matter the negative or not. So that gives us 6 pairs not 3.
