Answer:
   5 2/5
Step-by-step explanation:
Multiply by (3 3/5)x/(1 1/2):
   x = (2 1/4)(3 3/5)/(1 1/2) = (9/4)(18/5)(2/3) =27/5
   x = 5 2/5

In AAA (Angle-Angle-Angle), triangles do not have the same size and only have 3 pairs of congruent angles.
In SSS (Side-Side-Side), if the three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent.

7978 years
Step-by-step explanation:
A = A02^(-t/hl)
where hl = half-life. 
Dividing both sides by A0 and taking the logarithm, we get
ln(A/A0) = -(t/hl)ln2 
or solving for t,
t= -(hl)ln(A/A0)/ln2
note that A/A0 = 0.38
t = -(5715 yrs)[ln(0.38)/ln2]
 = 7978 years
