Answer:

(-2,-4)

Step-by-step explanation:

3x-2y=2

5x-5y=10

--

Multiply 3x-2y=2 by -5 to turn it into -15x+10y=-10

Mutiplu 5x-5y=10 by 2 to turn it into 10x-10y=20

--

Eliminate y

-15x+10y=-10

10x-10y=20

= -5x=10

Divide by -5

x=-2

--

Plug -2 to the first equation

3(-2)-2y=2

-6-2y=2

Move -6 to the other side by adding 6 to both sides

-2y=8

Divide by -2

y=-4

(x,y) = (-2,-4)

You can sand frac{4}{9}
Reptile [31]

Answer:

Step-by-step explanation:

2 and 38/45 square yards can be sanded in 3.2 hours.

Step-by-step explanation:

1/2 of an hour is 30 minutes. so 4/9 for every 30 minutes. 1 hour is 8/9. So 3 2/10 would be 3 hours =24/9=2 6/9 and 2/10 would be ( if 5/10 is 30 minutes then 2/10 is 12 minutes.) 8/9 x 1/5 = 8/45. (24 x 5 = 120) 120/45 + 8/45 is 128/45 = 2 38/45

Which of the following represents, the difference of a number squared and four is less than or equal to five.
LekaFEV [45]

Answer:

x² - (4 ≤ 5)

Step-by-step explanation:

(I have x representing the number that is squared, it might be a different letter on your options, but regardless it will be the same general answer. You also may not need the parentheses around the 4 ≤ 5)

Difference means subtraction so we know that the second number/group of numbers will be subtracted from the first that is listed.

Next, if you are squaring any number it's going to have the little 2 to the right of it. That's what that means.

Then, we look at that last bit. <em>"Four is less than or equal to five."</em> This means exactly how it sounds. To write this we need the symbol ≤. This symbol means less than or equal to. You would would but the 4 in front and the 5 in back to get 4 ≤ 5.

Now we just put it together. It tells us that 4 ≤ 5 is being subtracted from a number squared. So this means that a number squared needs to be first, and because difference means subtraction, we would subtract 4 ≤ 5 from that. A number squared can be represented by any letter variable, but for this example, I will use x.

This leaves you with x² - (4 ≤ 5)

I hope this helped :)

Lucas wants to use the box with the greatest volume
stiks02 [169]

*see attachment for the possible choice answers showing the boxes and dimensions

Answer:

Box D = 27 ft³

Step-by-step explanation:

To find out which has the greatest volume, we need to calculate the volume of each box given in the option using the formula of the volume of a rectangular prism = w × h × l.

Where w = width; h = height; and l = length.

Thus, the volume for the boxes are as follows:

=>Box A:

V = w × h × l

V = 3 × 1 × 5

V = 15 ft³

=>Box B:

V = w × h × l

V = 2 × 3 × 4

V = 24 ft³

=>Box C:

V = w × h × l

V = 1 × 2 × 7

V = 14 ft³

=>Box D:

V = w × h × l

V = 3 × 3× 3

V = 27 ft³

The shipping box with the largest volume is box D with a volume of 27 ft³
