### Answers

X-.15x=2210 x=the original price .15x is the original price with the times 15%

x(1-.15)=2210

x=2210/(1-.15)

x=2210/.85

x=2600

You would get a calculator and subract the 15% discount

What is 697*100 please help

### Answers

Here is a trick I always use:

Get rid of both zeros in100 for now

So just do 697*1 which is just 697

Now add the two zeros to your answer to get 69,700 which is the final answer

You just want to multiply the two numbers together, so the answer would be 69,700.

(Also, there's a shortcut when multiplying by multiples of ten, such as 10, 100, 1,000, 10,000 etc. Just add on the number of zeros that you see to the number which doesn't have the zeros in it. In this example, add two zeros (present in the 100) to the number 697, which will give you 69,700)

Hope this helped! Good luck!! :)

-7x-2y=-13 and x-2y=11

Substitution method

### Answers

X - 2y = 11

x = 11 + 2y

Now, substitute the value of x in first equation,

-7x - 2y = -13

-7(11 + 2y) - 2y = -13

-77 - 14y - 2y = -13

-16y = -13 + 77

y = -64/16

y = -4

Now, substitute the value of y in 2nd equation,

x - 2y = 11

x - 2(-4) = 11

x + 8 = 11

x = 11 - 8

x = 3

In short, Your Answer would be: (3, -4)

Hope this helps!

Multiply one of them by -1 so one of the -2y is positive

-1(-7x-2y=-13)=7x+2y=13

Then add the two equations

7x+2y=13

+ x-2y=11

========

8x=24 - the 2y and -2y cancel out. Now solve for x

x=3 Now plug the x back into one of the equations

3-2y=11 Now solve for y

-2y=11-3

-2y=8

y=-4

So x=3 and y=-4

Hope this helps!

An electronics company packages its product in cube-shaped boxes. These boxes are placed into a larger box that measures 3 ft long, 114 ft wide, and 2 ft tall. The edge length of each cube-shaped box is 14 ft. How many cube-shaped boxes can fit into the container? A.240 B.480 C.720 D.960

### Answers

Answer:

480

Step-by-step explanation:

Dimensions of larger box

Length = 3 feet

Width =

Height = 1/4 feet

Volume of larger box = length * width * height

=

The edge length of each cube-shaped box placed in larger box is 1/4 ft.

Volume of smaller cube

Where x is the edge length

Volume of smaller cube

No. of smaller cubes can be place in larger box

Hence 480 cube-shaped boxes can fit into the container

The answer is b.480 and i hope u get a good grade

A computer that originally cost $850 is on sale for 15%off. What is the sale price of the computer show your work

### Answers

If it is on sale for 15%, then you are paying 85% (100-15) of the original price.

To find 85% of 850, you do 850*.85 to get $722.50

Hope this helps

(850)x(0.85)=722.50

By multiplying the original price by .85 you get the sale price with the 15% off.

it costs luis $5 to park his car at a parking meter for 2 hours. what is the price to park for 1 hour? write and solve an equation for this situation.

### Answers

The equation can be:

5=2x (x is the number of hours)

If you divide both sides by 2 you get x=5/2 or 2.5

So the answer is $2.50 per hour

So I did 5/2 and I got 2.5

5 divided by 2 = 2.5

Not 100% sure if I'm right though

The pyramid shown has a square base that is 32 centimeters on each side. The slant height is 24 centimeters. What is the lateral surface area?

### Answers

L.S.A.=1/2pl where p represents the perimeter of the base and l the slant height.

L.S.A. = ½(4*32)(24)

L.S.A. = ½ (128)(24)

L.S.A. =1/2(3072)

L.S.A. = 1536 cm

I know the answer your looking for is 1536cm hope this helped have a nice day :)

A prism is completely filled with 2304 cubes that have edge length of 14 cm What is the volume of the prism?

### Answers

the prism is filled completely, that means volume of prism = sum volume of cubes

volume of a cube =h^3, volume of eachcube = 14cmx14cmx14cm=2744cm^3

volume of 2304cubes = 2304 x 2744cm^3=6322176cm^3

so the volume of prism =6322176cm^3
