W=t times 8 :)
When you are solving the equation you see that after 9 minutes there is 72 inches to find the unit rate you divide 9 by 72 and you get 8 so per each minute there is 8 inches of water

Julius is buying beverages for brunch. He needs to buy a total of 5

xeze [42]

Well, he only needs 5 gallons of beverages. Because he buys two containers of each, however, that means he bought 320 gallons total (I would say). How I got my answer:

There are 8 pints in a gallon (8 x 2)
There are 4 quarts in a gallon (4 x 2)
There are 16 cups in a gallon (16 x 2)
There are 128 ounces in a gallon (128 x 2)

With that being said, we can add these to find the total amount of gallons of beverages Julius bought. 16 + 8 + 8 + 32 + 256 = 320.

Hopefully this helps!

Rachel has tossed a fair coin ten times. It landed heads up every time. Is this POSSIBLE?

devlian [24]

Yes, although this is unlikely as every time she flips the coin there is a 50% chance of getting heads. Therefore, there is a possibility of her getting heads every time

A shirt that cost $420 was discounted 20% for Bloomingdale's one day sale. When the sale was over, the shirt was marked up 20%.

Maurinko [17]

Answer:

$504

Step-by-step explanation:

Step one:

given data

A shirt that cost $420

we are told that the shirt was on a discount sale of 20%, so when the discount is over the price will return to $420, we are then told that the shirt was marked up 20%.

Step two:

Hence the new cost is

=20/100*420+ 420

=0.2*420+420

=84+420

=$504

One number is 2 more than 3 times another. Their sum is 22. Find the numbers.

ivolga24 [154]

Make a system of equations.

$\sf~x=3y+2$
$\sf~x+y=22$

Re-arrange the 2nd equation:

$\sf~x+y=22$

Subtract y to both sides:

$\sf~x=-y+22$

Plug in -y + 22 for 'x' in the first equation.

$\sf~x=3y+2$

$\sf~-y+22=3y+2$

Subtract 3y to both sides:

$\sf~-4y+22=2$

Subtract 22 to both sides:

$\sf~-4y=-20$

Divide -4 to both sides:

$\sf~y=\boxed{\sf5}$

Plug this into any of the two equations to find 'x':

$\sf~x+y=22$

$\sf~x+5=22$

Subtract 5 to both sides:

$\sf~x=\boxed{\sf17}$

So one of the numbers is 5 and one of them is 17.
