When given the scale factor and the factored size of the object, to find the original size, divide the factored size by the scale factor:
0.8 / 3.1 = 0.258 inches
Answer:
Step-by-step explanation:
m∠AOB+m∠BOC=180°
m∠AOB=8x+51°
m∠BOC=6x-25°
~





m∠AOB:-



Therefore, m∠AOB=139°
Let
A------------> <span>number of children
B------------> </span><span>number of adults
we know that
0.40A+0.70B=5.90--------------------------> equation 1
A+B=11------------> A=11-B----------------> equation 2
using a graph tool------------> to resolve the equations system
see the attached figure
the solution is
A=6
B=5
the answer is
A is bigger</span>
