Answer:

1200

Step-by-step explanation:

Faceti o ecuatie pentru a o rezolva mai usor:

Intrebarea spune ca o treime a fost pentru un tricicleta si o a treia pentru o bicicleta, deci acestea sunt aceeasi valoare. Y este totalul.

    x + x + 400 = y

Exista trei parți ale ecuației și intrebarea spune ca doua treimi sunt utilizari pe bicicleta și tricicleta. Trebuie sa ramana o treime, deci pe a treia (x) trebuie sa fie aceeași cu 400.

Faceți o noua ecuație:

400 + 400 + 400 = ?

Adaugați numerele pentru a obține raspunsul: 1200

tatuchka [14]

Answer:

Marion bought 6  frog lures and 8 lizard fishing lures.

Step-by-step explanation:

Let f represent frog lures and l represent lizard lures.


The total packages Marion bought is

f+l=14...eqn1


If she bought frog lures in packages of 4 and lizard lures in packages of 6 for a total of 72 lures, then

4f+6l=72...eqn2


We make f the subject in equation 1 and put it into equation 2 to get;

f=14-l...eqn3


We put equation 3 into equation 2 to get;

4(14-l)+6l=72


\Righttarrow 2(14-l)+3l=36


We expand the bracket to get;

28-2l+3l=36


-2l+3l=36-28


l=8


We put l=8 into equation 3 to get;

f=14-8


f=6

Therefore Marion bought 6  frog lures and 8 lizard fishing lures.
