Si debes tomar 0.035 litros de agua por cada kg de peso al día, si pesaras 50 kg ¿Cuánta agua deberás beber en un día? ayuda porfavor

Answers

Answer:

Deberás beber 1.75 litros de agua en un día.

Step-by-step explanation:

Answers

Answer:

Step-by-step explanation: B

The tables of ordered pairs representing relations that are functions are: A and C.

What is a Function?

If a table of ordered pairs of a relation has each x-value relating to exactly one y-value, then the relation is a function.

Table B and D do not apply to this rule. Table A and C have each of its x-values paired with exactly one y-value.

Therefore, table A and C represent functions.
