Answer:
0.025 Kg/ cm²
Step-by-step explanation:
if two variables vary inversely, there is a negative relationship between both variables. the increase in one variable leads to a decrease in the other variable
the equation that represents inverse proportion :
where b = constant of proportionality
to determine the answer in this question :
1. determine constant of proportionality
200 = k / 32
k = 6400
2. Determine the amount of pressure using the constant of proportionality
256, 000 = 6400 / pressure
pressure = 6400 / 256, 000 = 0.025
Delila is correct as she multiplying three negative numbers and determines that the solution will be negative.
As given in the question,
Let the three negative numbers be -x , -y , and -z.
Delia is multiplying three negative numbers
Multiply First two numbers
(-x) (-y) = + x y as (-)(-) = +
Multiply by third numbers
(+x y) (-z) = -x y z as ( +)(-) = -
Therefore, Delila is correct as she multiplies three negative numbers and determines that the solution will be negative.

BC must be equal to AD, so 4x+5=-3x+26. You must get all common terms on one side, so 7x=21. then divide to get x alone, and x=3.
