Answer:

9 trays

Step-by-step explanation:

for deli A, (9 trays * $7.50) + $18 delivery = $85.50

for deli B, (9 trays * $9.50) + $0 delivery = $85.50

if you need to check your other answers, substitute the 9 trays for another number and you'll see the end price is different.

IS THIS CORRECT!!!!!!!!!!!!!

<span> For this case, the first thing we must do is define variables.
 We have then:
 x: number of devices.
 Y: plan charge
 For the current plan we have: 
</span> y = 175&#10;
<span> For the new plan we have:
</span> y = 4.5x + 94&#10;
<span> Since we want the new plan to be smaller than the current plan, then we have:
</span> 175\ \textgreater \  4.5x + 94&#10;
<span> From here, we clear the value of x:
</span> 4.5x \ \textless \ 175 - 94&#10;&#10;x \ \textless \ 81 / 4.5&#10;&#10;x \ \textless \ 18
<span> Answer:
 x <18
 Note: The graph is correct</span>

What is x equal to? 4(4-3x)=4
inysia [295]

4(4 - 3x) = 4      <em>divide both sides by 4</em>

4 - 3x = 1     <em>subtract 4 from both sides</em>

-3x = -3     <em>divide both sides by (-3)</em>

<h3>x = 1</h3>

There are 8 performers who will present their comedy acts this weekend at a comedy club. One of the performers insists on being
Korvikt [17]
This is a permutations problem. There are only 7 comics you can move into different time slots, the 8th one being fixed in that last position. So you can look at it this way:
For the 1st position, you can choose from all 7 people. Once you've picked that one, you have 6 people to choose from for the 2nd position, and similarly for the remaining ones . This gives you 7x6x5x4x3x2x1 = 5040 ways to arrange them. And the last comic stays in the same position all the time so does not change this number. Make sense? If you need to demonstrate it to yourself, use a smaller number of comics, like 3 or 4, and write out the combinations to see that it works.
