Answer:
C. 772.5 kg
Step-by-step explanation:
We have been given that a hot air balloon holds 4,328 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic meter.
To find the amount of helium in the balloon, we will use density formula.
Upon substituting our given values, we will get:
Upon rounding our answer to nearest tenth, we will get:
Therefore, the balloon contains 772.5 kilograms of helium and option C is the correct choice.

Answer:
19
----- = x
40-3a
Step-by-step explanation:
3(ax + 9) = -4 (-2 - 10x)
Distribute
3ax +27 = 8+40x
Subtract 3ax from each side
3ax-3ax +27 = 8+40x-3ax
27 = = 8+40x-3ax
Subtract 8 from each side
27-8 = 8-8+40x-3ax
19 = 40x-3ax
Factor an x on the right side
19 = x(40-3a)
Divide each side by 40-3a
19/(40-3a) = x(40-3a)/(40-3a)
19
----- = x
40-3a
