3.- Una locomotora S/333 consume 39.9 litros de diésel para mover, en terreno plano, una carga de 1000 toneladas a 10 km
de distancia. Suponiendo que el terreno es plano, ¿Cuántos
litros de diésel consumirá para mover la misma carga a 80 y 200
km de distancia? Si ha consumido 478.8 litros, ¿qué distancia
ha recorrido?

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

4x and 6y

im not sure though

c

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
