Answer:

.13 cents per can

Step-by-step explanation:

If you bought 18 cans with $2.30, you need to divide 2.30 by 18 becauseyou need to find out the unit price for each can. When you divide .2.30 by 18 you get .1277777repeaing so you can just round up from there and get .13 cents.

Find an ordered pair (x y) that is a solution to the equation calculator

galina1969 [7]

Pick a value for 'x' then solve for the 'y'

Ex: X=6 then 6-2y=2 then 4=2y then y=2y

So your answer will be 6,2.

Another answer to your question would be 4,1.

5x^2-2x=2<br>help plsmmm

Yuki888 [10]

Answer:

Presumably you're solving for x here? Without further information we'll assume that.

With that in mind, x is approximately equal to 0.86 and -0.46

Step-by-step explanation:

Let's start by putting it in the usual ax² + bx + c format.

$5x^2- 2x = 2\\5x^2 - 2x - 2 = 0\\$

let's solve it. First we'll multiply both sides by five, making the first term a perfect square:

$25x^2 - 10x - 10 = 0\\$

Now we'll add 11 to both sides:

$25x^2 - 10x + 1 = 11\\$

Which makes the left side a perfect square:

$(5x - 1)^2 = 11$

And now we can solve for x:

$(5x - 1)^2 = 11\\\\5x - 1 = \sqrt{11} \\\\5x = 1 + \sqrt{11}\\\\x = \frac{1 + \sqrt{11}}{5}$

Note that there's no apparent way of drawing the ± symbol when editing equations, so take that + sign as actually being ±.

That gives us two answers:

$x = \frac{1 + \sqrt{11}}{5}\\\\x \approx \frac{1 + 3.32}5\\\\x \approx \frac{4.32}5\\\\x \approx 0.86$ $x = \frac{1 - \sqrt{11}}{5}\\\\x \approx \frac{1 - 3.32}5\\\\x \approx \frac{-2.32}5\\\\x \approx -0.46$

The formula Upper V equals LWH is used to find the volume of a box. If the length of a box is increased 4 times, the width is i

marysya [2.9K]

Answer:

the volume of the box increases 48 times compared to the 1st one.

Step-by-step explanation:

Volume of the box (1) = LWH

length of a box is increased 4 time = 4L

width is increased 4 times = 4W
the height is tripled = 3H

=> The new volume of the box = 4L * 4W * 3H = 48LWH

So the volume of the box increases 48 times compared to the 1st one.

Beyonce's private jet can fly 1800 miles in 2 hours at a constant speed.

lukranit [14]

Answer:

im not too sure but my best guess would be

D= 900×T

D= the constant of proportionality multiplied by time to get how many miles traveled.

if the hours given were 1 hour 2 hours & 3 hours

if you multiplied them by 900 you would get the distanced traveled

900 x 1 = 900 miles traveled in one hour

900 ×2 = 1800 miles traveled in 2 hours

sounds good ?
