3 + (-4) when you add or multiply or divide here are some things you should remember so you can understand it better

(-)(-) = +

(+)(-)= -

(+)(+)= +

(-)(+)= -

so now that you know this we can work on the equation

since there is a positive and a negative the answer has to be negative number and it automatically turns it to subtraction instead of addition so now its like  this 3 - (-4) so now subtract 3 - 4 which is 1 but since the 4 is a negative then the answer goes to -1

hope i helped i just want to understand it so you can do this on your on next time

goodluck

A hot air balloon holds 3,249 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic meter. How many kilogr
professor190 [17]
We find the answer by using the density formula: d  =m/v
We know the density: 0.1785
We know the volume: 3,249
We DO NOT know the mass, so that is what we're trying to finding
0.1785 = m/3,249
Solve:
3,249 * 0.1785 = m/3,249 * 3,249
579.9465 which can be rounded to 579.9
The answer is D.

yuradex [85]

Answer:

Amount water added = 4.5 L

Step-by-step explanation:

Amount of bane-berry = 3% of 9 L = 0.27 L

Computation:

Assume;

Amount water added = x L

Total solution = 9+x L

New percentage of bane-berry = 0.27x100/(9+x)
