Una cooperativa ha envasado 2000l de aceite en botellas de 1,5l y 2l. Sabemos que han utilizado 1100 botellas en total. ¿Cuántas se han necesitado de cada clase?

Step-by-step explanation:

x + y = 1100

x = 1100 - y

1.5× x + 2.1 × y = 2000

1.5x + 2.1y = 2000

Substituting

1.5(1100 - y) + 2.1y = 2000

(-5,-28)

i graphed to on desmos.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
