Answer:
102.8/4=25.7
I got it because I used a calculator
Step-by-step explanation:
Answer:
X=15
Step-by-step explanation:
A +B + C = 180
2x +4x+ 6x = 180
12x =180
X= 15
Answer:
x ∈ (-∞, -1) ∪ (1, ∞)
Step-by-step explanation:
To solve this problem we must factor the expression that is shown in the denominator of the inequality.
So, we have:

So the roots are:

Therefore we can write the expression in the following way:

Now the expression is as follows:

Now we use the study of signs to solve this inequality.
We have 3 roots for the polynomials that make up the expression:

We know that the first two are not allowed because they make the denominator zero.
Observe the attached image.
Note that:
when 
when 
and
is always 
Finally after the study of signs we can reach the conclusion that:
x ∈ (-∞, -1) ∪ (1, 2] ∪ [2, ∞)
This is the same as
x ∈ (-∞, -1) ∪ (1, ∞)
The answer you’re looking for is a yes the domain value five corresponds to two range values -8 and five
Answer:
5
Step-by-step explanation:
You <em>multiply</em> the number of people by the number of each slices each person gets. Which is 100; 50x2.
Each cake has 20 slices so you <em>divide</em> 100 by 20. Which equals 5.
It would take 5 cakes to feed all 50 people 2 slices each.
