Nx-5= -0.4 What is N?

denis-greek [22]

Answer:

$\large\boxed{n=\dfrac{4.6}{x}}$

Step-by-step explanation:

$nx-5=-0.4\qquad\text{add 5 to both sides}\\\\nx-5+5=-0.4+5\\\\nx=4.6\qquad\text{divide both sides by}\ x\neq0\\\\\dfrac{nx}{x}=\dfrac{4.6}{x}\\\\n=\dfrac{4.6}{x}$

Solve |2x - 5| = 4. {x | x = -4.5 or x = 4.5} {x | x = 0.5 or x = 4.5} {x | 0.5 < x < 4.5}

kotykmax [81]

Answer:

{x | x = 0.5 or x = 4.5}

Explanation:

Before we begin, remember that:

The modulus gives the positive value of what's inside it.

This means that:

|a| = |-a| = a

Now, for the given, we have:

|2x-5| = 4

From the above rule, we can deduce that:

either:

2x - 5 = 4

2x = 4 + 5 = 9

x = 4.5 ............> first solution

Or:

2x - 5 = -4

2x = 5-4 = 1

x = 0.5 ..........> second solution

Now, we check:

at x = 4.5: |2(4.5)-5| = |9-5| = |4| = 4 ..........> first solution verified

at x = 0.5: |2(0.5)-5| = |1-5| = |-4| = 4 .........> second solution verified

Hope this helps :)

While attending a film festival you decide that there are 13 movies that you are interested in seeing. However, you only have ti

A. 8,648,640
B. 13
C. 665,280
D. 4,324,320
Assume you don't watch movies twice.
If you have 13 movies to pick from, then you have 13 choices for the first movie. Then, only 12 choices are left. Do this until only 6 are left (13-7=6)
This equates to $13*12*11*10*9*8*7=8,648,640$
Therefore, the answer is A, 8,648,640 different ways.

Hope this helps!
