Una cadena farmacéutica ofrece un paquete de insumos para la elaboración de alcohol en gel, insecticidas y pesticidas. El costo de este paquete es de $325000, e incluye insumos para elaborar 500 litros de insecticidas, 750 litros de pesticidas y 350 litros de alcohol en gel. Calcular el precio por litro de cada producto, sabiendo que los insumos para elaborar 1 litro de pesticida cuesta el triple que 1 litro de insecticida, y que 1 litro de alcohol en gel cuesta igual que 3 litros de pesticida más 1 litro de insecticida.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
