Virty [35]3 years ago

Answer:

No

Step-by-step explanation:

y = 3x + 4      If x=2   And    y=10

10 = 3*2 + 4

10 = 10           that’s a solution for this equation

y = x + 7      if x=2    and    y=10

10 = 2 + 7

10 (is not) = 9       That’s not a solution for this equation.

Martina, Jim, and Scott served a total of 121 orders Monday at the school cafeteria. Martina served 6 more orders than Scott. Ji
iris [78.8K]

Answer:

Martina 29, Scott 23 and Jim 69.

Step-by-step explanation:

We are told that:

Martina served six more X orders than Scott (X+6).

So, Scott served X orders.

And Jim served 3 times X order as Scott.

We will have then:

X + (X+6) + 3X = 121

5X + 6 = 121

5X = 121 - 6

5X = 115

X = 115/5

X = 23

So, Scott served 23 orders, Martina 29 and Jim 69.

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.

Find the formula for the nth term of the arithmetic sequence -39, 61, 161, 261, ...
maksim [4K]
<h3>Given that it is arithmetic</h3>

d = a_{2} - a_{1} = 61 - ( - 39) = 100

a_{n} = a_{1} + (n - 1)d \\ a_{n} = - 39+ 100 (n - 1) \\ a_{n} =  - 39 + 100n - 100 \\ a_{n} =  - 139 + 100n
