So,
If she keeps one-fourth for herself, she will keep:
72 * 0.25 = 18
That leaves the rest for her friends.
72 - 18 = 54
Her friends will get 54 "Suites."
Answer:
B.
Step-by-step explanation:
The first number minus the 2nd number will close off the distance.
If you have an angle and want to know its complement, you subtract it from 90 degrees. What angle, when subtracted from 90 degrees, gives the same value?
90 - x = x
The supplement of x is the angle that you add to x to make 180 degrees. In other words, 180 - x = the supplement of x.
X = pens and y = pencils
4x + 7y = 13.25
y = 0.75
4x + 7(0.75) = 13.25
4x + 5.25 = 13.25
4x = 13.25 - 5.25
4x = 8
x = 8/4
x = 2 <===so each pen cost 2 bucks
Answer:
No solution
Step-by-step explanation:
We have

For the sum it is not correct to assume

Note that for

it is assumed
and in your case
for 
In fact, considering a set
we have
that satisfy 
This means that, by definition 
Therefore,

because the sum is empty.
For

we have other problems. Actually, this case is really bad.
Note that
has no value. In fact, if we consider for the case
, the cosine function oscillates between
, and therefore it is undefined. Thus, we cannot evaluate

and then

has no solution
