5 Muñecas costaron $130 ¿Cuantas muñecas se podran comprar con $390 a 130$

For this case we have that, the cost of 5 dolls is $130. If we want to know the number of dolls that can be bought with $390 we make a rule of three:

5 dolls -----------> $130

x --------------------> $390

Where the variable "x" represents the number of dolls that can be purchased with $390.

Thus, you can buy 15 dolls.

15 dolls

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
