The answer is 8x.
You are combining like terms as 5 and 3 both have x so you are simply adding 5+3= 8
Answer:
Step-by-step explanation:
Since we believe it
The number sequence is that those which can be described as 
and that is not ending and recurring. Figures that are unreasonable are also the ones, that are not and therefore are non-ending, non-recurring.
The number sequence is 
Rational amount since it is classified as .
is really a rational number.
is a real function, since it does not end but repeats it.
The rational number 
Unreasonable number 
.

The equation which can be used to find the number of quarters and nickels is; n + q = 84, 0.05n + 0.25q = 17.80.
<h3>Quarters and nickels</h3>
- Total coins = 84
- Total value = $17.80
let
- Number of quarters = q
- Number of nickels = n
n + q = 84
0.05n + 0.25q = 17.80
From equation (1)
n = 84 - q
Substitute into (2)
0.05n + 0.25q = 17.80
0.05(84 - q) + 0.25q = 17.80
4.2 - 0.05q + 0.25q = 17.80
- 0.05q + 0.25q = 17.80 - 4.2
0.20q = 13.60
q = 13.60 / 0.20
q = 68
Substitute q = 68 into
n + q = 84
n + 68 = 84
n = 84 - 68
n = 16
Therefore, the number of quarters and nickels are 68 and 16 respectively.
