How do I solve -6n+3n=-18

Mathematics

DENIUS [597]4 years ago

You add the alike variables first so -6n + 3n = -3n

then the equation is -3n=-18
Now divide each side by -3 to get the n by itself

-3n     -18
---   = ------
-3         -3


n=6

First simplify. Combine like terms

-6n + 3n = -3n

-3n = -18

Isolate the n, divide -3 from both sides

-3n/-3 = -18/-3

n = -18/-3

n = 6 (remember, in dividing two negative numbers, the answer will be positive).

6 is your answer

hope this helps

The value 13 is 200% of
tia_tia [17]
This would be in terms of dividing the largest number (being 13) by the percentage in decimal form.

The percentage worked where you take that and divide by 100 to get your percentage, meaning:

13/2 = 6.5 | 13 is 200% of 6.5. Because if you double it you get 13 which is how 200% works.

I hope this helps, have a great rest of your day! ^ ^

1) Where is the midpoint of , when A (6, 7) and B (-9, -5)?
lord [1]

Answer:

(−1.5,1)

Step-by-step explanation:

Finding the distance, midpoint, slope, equation and the x y-intercepts of a line passing between the two points p1 (6,7) and p2 (-9,-5)

The distance (d) between two points (x1,y1) and (x2,y2) is given by the formula

d = √  ((X2-X1)2+(Y2-Y1)2)

d = √ (-9-6)2+(-5-7)2

d = √ ((-15)2+(-12)2)

d = √ (225+144)

d = √ 369

The distance between the points is 19.2093727122985

The midpoint of two points is given by the formula

Midpoint= ((X1+X2)/2,(Y1+Y2)/2)

Find the x value of the midpoint

Xm=(X1+X2)/2

Xm=(6+-9)/2=-1.5

Find the Y value of the midpoint

Ym=(Y1+Y2)/2

Ym=(7+-5)/2=1

The midpoint is: (-1.5,1)
