Dimes (0.10): 5Q

Quarters (0.25): Q

 Dimes  + Quarters = Total

0.10(5Q) +  0.25(Q)  = 5.25

0.50Q    +  0.25Q    = 5.25

         0.75Q             = 5.25

         \frac{0.75Q}{0.75}            = \frac{5.25}{0.75}

                Q              = 7

Answer: 7 quarters

El perímetro de un rectángulo es 28cm, uno de los lados es 6cm más que el otro lado. Hallar el mayor lado del rectángulo.
son4ous [18]

Answer: El mayor lado del rectangulo tiene 10cm

Step-by-step explanation:

El perímetro de un rectángulo puede escribirse como:

P = 2*L + 2*A

Donde L es el largo y A es el ancho.

Sabemos que uno de los lados es 6cm mas largo que el otro, entonces podemos escribir:

L = A + 6cm.

P = 28cm = 2*L + 2*A

podemos reemplazar la primera ecuación en la segunda:

28cm = 2*(A + 6cm) + 2*A

28cm =  12cm + 4*A

28cm - 12cm = 4*A

16cm/4 = A

4cm = A.

Entonces el ancho es 4 cm, y el largo es L = 4cm + 6cm = 10cm
