You do 28-12 to find out how much girls there are then you get 16 and you have the ratio of 12/16 then divide by 4. Then you get 3/4 boys to girls
K= 1/12
perimeter of doll house= 36 inches
:. length of doll house= 36inches / 4
= 9 inches
length of actual= length of doll house x k(inverse)
:. actual lenght= 9 inches x 12/1
= 108 inches
Answer:-2x^2+3x-7=0
Step-by-step explanation:
The complete question in the attached figures N 1 and N 2
we have that
<span>the following system of inequalities:
y ≥ −3x + 1
y ≤ (1/2)x + 3
using a graph tool
see the attached figure N 3
the answer is the option
