Answer:

When m = 16 and n = 4, m - 2 * n + 2 = 10.

Step-by-step explanation:

m - 2 * n + 2

Substitute values given

m = 16

n = 4

16 - 2 * 4 + 2

Multiply -2 and 4.

16 - 8 + 2

Subtract 8 from 16.

8 + 2

Add 8 and 2.

10.

If the original expression had parenthesis, please let me know as this answer would need to be edited.

-3/v=-6 simply as much as possible

Hey!

In order to simplify this equation, we'll first have to multiply both sides of the equation by v. This will give us v on its own.

Original Equation :
$\frac{-3}{v} = -6$

New Equation {Added Multiply Both Sides by V} :
$\frac{-3}{v} v=-6v$

Solution {New Equation Solved} :
$-3 = -6v$

Now we'll switch sides to get v on the left side of the equation which is generally where we always want the variables to be located in these types of equations.

Old Equation :
$-3 = -6v$

New Equation {Switched} :
$-6v=-3$

Now we'll divide both sides by v to get v on its own.

Old Equation :
$-6v = -3$

New Equation {Added Divide Both Sides by V} :
$\frac{-6v}{v} = \frac{-3}{v}$

Solution {New Equation Solved} :
$v = \frac{1}{2}$

So, this means that in the equation $\frac{-3}{v} =-6$ , $v = \frac{1}{2}$ .

Hope this helps!

We know that they have:

8 gates
and again 3 ways to chose (escalator, elevator and stairway)

now you have to multiply it:
$2*3*8*3=6*8*3=48*3=144$

There are 144 different ways that Anita and Terry can go from street level to the trains:)
