Answer: Choice B) The expression (10-2x)(30-2x)x represents the volume of the box

----------------------------------------------------
----------------------------------------------------

The original width is 10 inches. The width reduces to 10-2x inches after we cut off the top two corners of the rectangle. We can think of it as taking 10 and subtracting off two copies of x like so: 10-x-x = 10-2x

Similarly, the length goes from 30 inches to 30-2x inches. This time we're taking off the top and bottom corners (focus on either side it doesn't matter). 

The height of the box is x inches due to this portion being folded up. 

Volume of box = (width)*(length)*(height)
Volume of box = (10-2x)(30-2x)x

Note: the units for the answer are in cubic inches which can be written as "in^3" (inches cubed).

What is the solution to the following equation? -6(x-2) + 3x = -3(x + 3) + 21
NeX [460]

9514 1404 393

Answer:

  no solution

Step-by-step explanation:

Simplifying the given equation, you have ...

  -6(x -2) +3x = -3(x +3) +21 . . . . . given

  -6x +12 +3x = -3x -9 +21 . . . . . . eliminate parentheses

  -3x +12 = -3x +13 . . . . . . . . . . . . collect terms

  0 = 1 . . . . . . . . . . . . . add (3x-12) to both sides

There is no value of x that will make this true.

The equation has NO SOLUTION.

A bicycle that usually sells for $230 is on sale for 25% off. What is the sale price?
zloy xaker [14]
The answer is $57.50.

Explanation:
To find the discounted price of an item, you multiply the original sell price of the item by a decimal version of the percentage. So in this case you would multiply .25 by 230 to get 57.5 or $57.50.

I hope I helped and good luck!

What percent of the total budget is the car (to the nearest tenth)
il63 [147K]

Answer: first option

Step-by-step explanation:

You can observe in the figure that the total budget is $1,695.00 and the car is $272.00

Then, you know that the total budget represents the 100%, then, to calculate what percent of the total budget the car is, you need to divide  $272.00 by  $1,695.00 and multiply this by 100:

\%car=\frac{ \$272.00}{ \$1,695.00}*100\\\\\%car=16.04\%

Rounded to the nearest tenth:

\%car=16.0\%
