Answer:

10

Step-by-step explanation:

I simply divided 140/14 and got 10! Hope this helps :)

The 140 percentage of the number 10 is 14

Given data ,

To find the number that is 140% of another number, we can set up the equation:

140% of x = 14

So , 140 percentage of the number x = 14

To solve for x, we need to convert 140% to its decimal form, which is 1.40:

1.40 * x = 14

Now we can solve for x by dividing both sides of the equation by 1.40:

x = 14 / 1.40

Dividing 14 by 1.40 gives us:

On simplifying , we get

x = 10

Therefore , the value of x = 10

Hence , 140 percentage of 10 is equal to 14

Answer:

-11/6

Step-by-step explanation:

Slope can be found with this equation:

(y₁ - y₂) / (x₁ - x₂)

What this essentially tells us to do is to put one set of the x and y coordinates into x₁ and y₁, respectfully. Then, put the other set of x and y points as x₂ and y₂.

With this scenerio, we can substitute the given points into the formula.

(6 - (-5)) / (-4 - 2) =

(6 + 5 ) / (-6) =

11 / (-6) =

-11/6

The slope is  - 11/6
