25%=0.25
24*0.25=6
24-6=18
18 pairs are not black

24 x .25 = 6
24 - 6 = 18
pair = 2
18/2 = 9

Hope This Helps! :D

Stan a local delivery driver is paid $3.50 per mile driven plus a daily amount of $75. on monday he is assigned a route that is

ozzi

So find the numbers it gives you
3.50$/per mile +75$
30 miles
per means multiply
(3.50*30)+75
105.00+75
he is paid 180.00$ for driving on monday

In your own words explain how you would solve this two step equation for the variable x. 9x-7=-7

NeX [460]

Answer:

Add 7 to both sides

Step-by-step explanation:

The equation has to be just x = y

There cannot be another number on the same side as the variable

Now that we did that, the equation is 9x = 0

x = 0

Well, that was easy lol

PLZ HELP ME. WILL GIVE BRAINLIEST. THANKYOU!!

____ [38]

Answer:

x = 6

Step-by-step explanation:

Given

3x + 30 + x = 10 + 2x + 5x + 2 , simplify both sides

4x + 30 = 7x + 12 ( subtract 7x from both sides )

- 3x + 30 = 12 ( subtract 30 from both sides )

- 3x = - 18 ( divide both sides by - 3 )

x = 6

Two lines, A and B, are represented by the equations given below!

lara [203]

Answer:

The solutions to the system of equations are:

$y=-8,\:x=-4$

Thus, option C is true because the point satisfies BOTH equations.

Step-by-step explanation:

Given the system of the equations

$\begin{bmatrix}y=x-4\\ y=3x+4\end{bmatrix}$

Arrange equation variables for elimination

$\begin{bmatrix}y-x=-4\\ y-3x=4\end{bmatrix}$

$y-3x=4$

$-$

$\underline{y-x=-4}$

$-2x=8$

$\begin{bmatrix}y-x=-4\\ -2x=8\end{bmatrix}$

solve for x

$-2x=8$

Divide both sides by -2

$\frac{-2x}{-2}=\frac{8}{-2}$

$x=-4$

$\mathrm{For\:}y-x=-4\mathrm{\:plug\:in\:}x=-4$

$y-\left(-4\right)=-4$

$y+4=-4$

$y=-8$

The solutions to the system of equations are:

$y=-8,\:x=-4$

Thus, option C is true because the point satisfies BOTH equations.
