1 kilo = 0.001 metric tons
So,if you had 4 kilograms,it would be 0.004 metric tons. If you had 12 kilograms,it would be 0.012 metric tons. You're dividing how ever many kilos by 1000.
Since
is negative, it doesn't have any real roots.
One is c and 2 is c.
1. 82-180=98
2.2x+28=6x-4 ---> x=6 plug 6 in for x and the answer is 40
Exact Form: t = 8/5
Decimal Form: t = 1.6
Mixed Number Form: t = 1 3/5 (one and three fifths)
4x^2 -28c + 40 = 1
-28c = 1 -4x^2 -40
-28c = -39 -4x^2
c = 39/28 + 4/28x^2
c = 39/28 + 1/7x^2 => answer
