None of these is correct.
-4(5-x)
= (-4•5) + (-4•-x)
= -20 + 4x
= 4x-20
Answer:
66 x 1/11 = 6
or
66 x 0.09 = 6
So x = either 1/11 or 0.09
Never
they have the same ratio only
congruent triangles have equal sides
The average rate is (4%*2+8%)/3=16/3%=5-1/3%
Therefore the original investment was
3664/(16/300)=300*3664/16=68700,
of which 1/3 was at 8% = 22,900
and 2/3 was at 4% = 45,800
Check:45,800*.04+22,900*.08=3664 yay!
First you have to find the last side of it.
P= 182
