Answer:
one-tenth
Step-by-step explanation:
one-half minus two- fifths
Check the picture below.
let's bear in mind that the segment MN is simply the sum of MQ + QN, and since M and N are midpoints, they cut that respective section into two equal halves.

Answer:
{-5/4, 8}
Step-by-step explanation:
We are given (4u + 5)(8 - u) = 0. Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:
4u + 5 = 0 leads to u = -5/4, and
8 - u = 0 leads to u = 8.
The solutions are {-5/4, 8}
It is definitely an isosceles triangle. when you plot it in a graph you will see that AB=BC=CA or AC.All the sides will be equal.
So essentially, we have a choice of :
2 reception halls
3 DJs
2 catering companies.
In order to find the number of arrangements, you need to multiply those : 2*3*2=12- So they have 12 arrangements.
why?
Imagine those 3 Djs- they are three arrangements.
Now, they can play in one or the other hall -so in total it's 3 Djs in one hall and 3 in the other -that's 6.
And all of those 6 possibilities can be catered by one or the other company- making the possibilities twice as many, so it's 12 in total!
