2/5 of a number is -8 what is the number

-20

Step-by-step explanation:

let x be the whole. 2/5 of x = -8 so -8 1/5 is -4. -4*5 to find the whole so its -20

The number is 35

If 2/5 of a number is 14, then we will perform a function of cross multiplication in order to determine the missing number.

Step-by-step explanation:

Let the missing number = y

To perform a cross multiplication, firstly, we multiply the numerator of first fraction by the denominator of the second fraction.

Secondly, we multiply the denominator of the first fraction by the numerator of the second fraction. Then, the resulting values are divided by each other to get a final numerical value.

Therefore, the missing number (y) will the denominator of the second fraction i.e. 14/y . The first fraction is 2/5.

Thus,

2/5 of 14/y

2/5= 14/y

(2 x y) = (5 x 14)

(2y) = (70)

2y = 70

Since we are looking for value of y, divide both sides by the value beside y

Thus,

2y/2 = 70/2

y = 35

Therefore, the missing number is 35

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
