What is the value of n? -10 = n/-0.2

Answers

-10 = n/-0.2

First, we can change the fraction n/-0.2 into a whole negative. Basically, move the negative sign to the front of the fraction.
$-10 = -(n)/(0.2)$

Second, we can now make our goal to get the variable (n) by itself on one side of the problem. This means we have to move everything over on another side. We can start out by multiplying both sides by 0.2.
$-10 * 0.2 = -n$

Third, let's simplify -10 × 0.2. Whatever the solution, it will be negative. You can solve this by using a calculator, set it up the long way, etc. (-10 × 0.2 = 2)
$-2 = -n$

Fourth, our last step is to multiply both sides by -1. Where did we get the -1? -n can be considered -1, since a variable by itself is 1. After this, we can switch sides.
$n = 2$

Answer: $\fbox {n = 2}$

n=2 2/-0.2 equals -10

In a relay race, 5 friends ran an equal share of the distance. The total distance of the race was 3 miles. What is the distance that each friend ran

Answers

3/5 = 0.60 miles

Each friend ran 0.60 miles

Well, you have to divide 5 by 3.

5 / 3 = 1.66

Now lets check it.

1.66 x 3 = 4.98

That should get you close enough to an answer.

4x - 3y = 15
2x + 2y = 4

what is the solution of the system of equations?

Answers

Answer:

System of Linear Equations entered :

[1] 4x - 3y = 15

[2] 2x + 2y = 4

Step-by-step explanation:

// Solve equation [2] for the variable y

[2] 2y = -2x + 4

[2] y = -x + 2

// Plug this in for variable y in equation [1]

[1] 4x - 3•(-x +2) = 15

[1] 7x = 21

// Solve equation [1] for the variable x

[1] 7x = 21

[1] x = 3

// By now we know this much :

x = 3

y = -x+2

// Use the x value to solve for y

y = -(3)+2 = -1

Solution :

{x,y} = {3,-1}

Answer:

{3,-1}
