Answer:

The minimum number of teachers needed is 6

Step-by-step explanation:

To find minimum number of teachers we have to divide 100 and 15 so the answer is 6.666.....but if we

multiply 6 and 15 we get 90 , so it means that 6 teachers can only provide for 90 students , unfortunately there are 100

students , so we need 1 more teacher for the rest ten students that's why the answer came in decimal point . so the answer could be 6.66 or 7 .

Describe a real-world situation that can be modeled by the function y=2x-3.
lara [203]

Yes you have a good example.

x = number of cookies

2*x = total amount spent on cookies at $2 each

2x-3 = amount you pay after the $3 discount is applied one time for the entire order

-------------

a more numeric example may be this

Lets say you bought 12 cookies, so x = 12

This means it costs 2*x = 2*12 = 24 dollars total if the discount doesnt apply

However, the 3 dollar discount is there, so the grand total is 24-3 = 21 dollars.

21. Angela until the same restaurant four times. Each time she ordered a salad and left at $ 5 tip. She spent a total of $ 54. W
Natalka [10]

So if Angela entered the same restaurant 4 times, we have 4 "instances" of her entering the restaurant.

Each instance, she ordered a salad. The price of this salad is unknown, so we'll say the price is "S".

Each instance, she payed a $5 tip.

So we have 4 instances of spending S, and 4 instances of spending 5.

We know this totals 54.

Knowing all of this information, we can write our equation like this:

4(S + 5) = 54

Divide

S + 5 = 13.50

Subtract

S = 8.50

The cost of salad is $8.50
