exact form: 8/3
decimal form: 2.6
mixed number form: 2 2/3
Answer: 5508
Step-by-step explanation:
all the numbers together equal 72 marbles in total.
(6x2)x (3x3)x (3x17)=
12 9 51 first multiply the easy numbers 12x9 =108 then
108x51= 5508
You need do like 25$--------100% of real price
x$---------70%
25x70=100<u>x</u>
1,750=100<u>x</u>
<u> x</u>=1750<u />divided by 100=17.5$
determinant: 
(a) 
D<0 means there are no real roots. there are two complex roots with imaginary components.
(b) D=16+20=36>0
D>0 means there are two real roots
(c) D = 20^2-4*4*25 = 0
D=0 means there is one real root with multiplicity 2
