Okay, I think I understand this. Our first step is to solve how long the string is after he used some of it to tie the package. I have a feeling we have to subtract 7/8 - 1/5. Find a least common multiple (in this case, it's 40) and our new fractions are 35/40 and 8/45. Subtract:
35/40 - 8/40 = 27/40.
I don't think this can be simplified down any further as they do not have any common factors. So with that in mind, let's divide 27/40 with 5/1 (5/1 is basically 5 wholes but in fraction version)
When dividing fractions, you want to use the KCF technique (my old math teacher taught me this). Keep the first fraction the same (in this case, 27/40), change the sign from multiplication to division, and flip 5/1 to get it's reciprocal, 1/5. The equation will look like this:
27/40 * 1/5 = 27/200
So each piece is about 27/200 m in length (or 0.135 m in length).
If this is wrong, please let me know, but this is what I got out of this question. I hope this helped you :)
Answer:
w = ( x - 10)
Step-by-step explanation:
area of the garden = x² - 25x + 150.
factorise the expression to find the x values.
x² - 25x + 150 = (x - 15)( x - 10) -15-10 = -25
-15*-10= 150
as the garden is rectangle, it's area will be = lw.
a = l × w
a = (x - 15)( x - 10)
one among them is the width, the other the length. if the length is (x - 15), then reasonably the width will be (x - 10).
hope this helps you, au revoir!
Answer(s):
<em>- p + (3p-5) + (4p+6)</em>

Esta es una pregunta de matemáticas?
1. 7
2. 15
3. 0
4. 5
Hopefully this is right, basically you are just turning negatives into positives I think.
