Answer:
(2,4) is a solution to this system of equations
Step-by-step explanation:
 Given system of equation are 


To find the solution of the given system of equations
To Check that (2,4) is a solution to this system or not
Solving equations (1) and (2)
From equation (1) and y=2x 
Now substitute y=2x is equation (2)






10-5x=0
-5x=-10

Substitute x=2 in equation (1)
y=2x
y=2(2)
Therefore y=4
Therefore the solution is (2,4)
Therefore (2,4) is a solution to the system of equations.
 
        
             
        
        
        
Answer:
42 ft
Step-by-step explanation:
 2(L + W ) = P
2 (12 + 9) = P
2 (21) = P
42 = P
P = 42
 
        
             
        
        
        
De ahí que la fracción de la mantequilla total que corresponde a cada postre sea 1/4
Si con 16 barras de mantequilla se prepararon 20 postres, esto se puede expresar como:
16 pegatinas = 20 postres
Para obtener la fracción del total de mantequilla que corresponde a cada postre, podemos escribir;
x = 1 postre
Divide ambas expresiones
16 / x = 20/1
20 veces = 16 * 1
20x = 16
x = 16/20
x = 4/5
De ahí que la fracción de la mantequilla total que corresponde a cada postre sea 1/4
