Step 3: 2y − 4 = 12

Which of these is most likely the next step?

2y = 3
2y = 8
2y = 16
2y = 18

It is -2.5 -- as you multiply them you'd get exactly positive 1.

Answer:

0.4

Step-by-step explanation:

Para preparar una empanada hay que añadir, entre otros ingredientes, 1/4 kg de atún, 1/6 kg de cebolla, 1/8 kg de pimiento rojo y 2/5 kg de tomates. a) Para una fiesta queremos llevar seis empanadas, ¿qué cantidad de cada ingrediente necesitaremos? b) Con 2 kg de pimiento rojo, ¿cuántas empanadas podríamos hacer?

Answers

Answer:

a. 1.5 kg of tuna, 1 kg of onion, 0.75 kg of red pepper and 2.4 kg of tomatoes

b. 16 empanadas

Step-by-step explanation:

Since each of these ingredients is needed and the recipe is for a single empanada, each ingredient in the recipe must be multiplied by 6 since they are 6 empanadas, like this:

1/4 kg tuna * 6 = 6/4 = 3/2 kg tuna

1/6 kg of onion * 6 = 6/6 = 1 kg of onion

1/8 kg of red pepper * 6 = 6/8 = 3/4 kg of red pepper

2/5 kg of tomatoes * 6 = 12/5 kg of tomatoes

Therefore 1.5 kg of tuna, 1 kg of onion, 0.75 kg of red pepper and 2.4 kg of tomatoes need it.

Now, with 2 kg of red pepper, what we should do is divide this quantity by the quantity for a recipe, like this:

2 / (1/8) = 16

that is to say that with 2 kg of red pepper, a total of 16 empanadas would be made
