200 grams, b/c 1.6 kg converted to grams is 1600grams, divided by 8 pots; therefore 200g
AD = BC ----> Parallel lines
AC = AC -----> Reflexive property
<A = <C -----> Congruent angles
<D = <B -----> Congruent angles
Isolate the variable by dividing each side by factors that don't contain the variable.
-6x-15+15=4x+35+15
-6x=4x+50
(Subtract 4 on both sides)
-10x=50
(Divide by 10 on both sides)
x=5
25 is the quotient I think haven't done this in 5 years
