Answer:
14.3€
Step-by-step explanation:
Let:
Now, let's write the data provided by the problem, using algebraic notation.
The total cost of the clothes is 20€, so:
The price of the shirt is :
Replacing this value into the first equation:
Solving for P:
So, the price of the pants is 14.3€ and the price of the shirt is:
Translation:
Deja que:
Ahora, escribamos los datos proporcionados por el problema, usando notación algebraica.
El costo total de la ropa es de 20 €, entonces:
El precio de la camisa es:
Reemplazando este valor en la primera ecuación:
Resolviendo para P:
Entonces, el precio del pantalón es de 14.3 € y el precio de la camisa es:
Step-by-step explanation:
f°g=
if the denominator is zero the number is undefined which makes it not in the domain of the function
set 
equal to 0
the values for x is 0 or 6
so the only value that is not in the domain of f°g is 0 and 6

You would earn 60 for 6 hours of work.
The common denominator would be 18. So, 5/6 becomes 15/18 and 7/9 becomes 14/18
The mean score (rounded to 2 DP) in the Math's test for class B is 86.86.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Class A has 15 pupils and class B has 29 pupils. The mean score for class A is 55. Hence:
Mean score of A = (sum of all scores) / 15
55 = (sum of all scores) / 15
sum of all scores in A = 825
The mean score for both classes is 76. Hence:
[(sum of all scores in A) + (sum of all scores in B)]/(total number of pupils) = mean score of both classes
[825 + (sum of all scores in B)]/(15 + 29) = 76
sum of all scores in B = 2519
Mean score of B = (2519) / 29 = 86.86
The mean score (rounded to 2 DP) in the Math's test for class B is 86.86.
