1. En equipos trabajen lo que se indica. a) Resuelvan las ecuaciones aplicando las propiedades de la igualdad y la propiedad distributiva que vieron en la lección anterior y completen la tabla. Ecuación 2(3x + 4) = 9 4(4z + 3) = 14 3(y + 3) = 2(2y + 4) 3(3x + 4) = 2(x + 7) Tabla 2.22 3(3n + 2) + 3n = 28.5 4(w + 3) = 2(w + 30.5)

Solve the system of equations. y= 2x y= x^2 - 15

The volume of gas a balloon can hold varies directly as the cube of its radius. imagine a balloon with a radius of 3 inches can hold 81 cubic inches of gas. how many cubic inches of gas must be released to reduce the radius down to 2 inches?

In a coastal town, the humidity, measured in grams of water per kilogram of air, increases by 43% for every 1 degree celsius increase in temperature. a scientist observes that the humidity on monday morning is 5.75 grams per kilogram. he wants to know how much the temperature must increase for the humidity to reach at least 49.17 grams per kilogram. let t represent the increase in temperature, in degrees celsius, from monday morning's observation. write an inequality to represent the situation, and use it to determine the desired temperature increase.
