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

Mathematics

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

3cis(5pi/4) in polar form
madreJ [45]
Rectangular form:
z = -2.1213203-2.1213203i

Angle notation (phasor):
z = 3 ∠ -135°

Polar form:
z = 3 × (cos (-135°) + i sin (-135°))

Exponential form:
z = 3 × ei (-0.75) = 3 × ei (-3π/4)

Polar coordinates:
r = |z| = 3 ... magnitude (modulus, absolute value)
θ = arg z = -2.3561945 rad = -135° = -0.75π = -3π/4 rad ... angle (argument or phase)

Cartesian coordinates:
Cartesian form of imaginary number: z = -2.1213203-2.1213203i
Real part: x = Re z = -2.121
Imaginary part: y = Im z = -2.12132034

P=2l+2w. solve for w. show all steps. please
aliina [53]

Answer:

Step-by-step explanation:

You need to get w on one side by itself.

Start out by subtracting 2l from both sides.

p−2l=2w.

Now since w is being multiplied by 2 we need to divided both sides (all terms) by 2.

w=p2−I

I’m not sure what the rule would be in this context, but those are just the squares of decreasing numbers starting at 10. It’s 10^2, then 9^2, then 8^2, and so on.
