There are 40 people in a room. The ration of men to women is 2:3. If 5 more men enter the room, what will the new ratio be?

7 : 8 (men to women)

Step-by-step explanation:

Ratio = 2 : 3 (men to women)

40 people in all

40 / 5 = 8

2 x 8 = 16 (men)

3 x 8 = 24 (women)

16 + 5 = 21

21 : 24

7 : 8

Hope this helps!

The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

IN SPANISH:

La gráfica de una función cuadrática es una parábola. El eje de simetría de una parábola es una línea vertical que divide la parábola en dos mitades congruentes. El eje de simetría siempre pasa por el vértice de la parábola. La coordenada x del vértice es la ecuación del eje de simetría de la parábola.

Step-by-step explanation:

Solving:

              −x + 2x

Rewrite;

              2x − x

              = x

Nice job guys!
