Answer:

There are N students in the class.

We know that ONLY ONE of the inequalities is true:

N < 10

N > 10

N < 22

N > 22

We want only one of these four inequalities to be true.

Remember that if we have:

x > y

y is not a solution, because:

y > y is false.

Then:

If we take N = 10, then:

N < 22

Is the only true option.

While if we take N = 22

N > 10

is the only true option.

So there are two possible values of N.

Think of your favorite spot to get food from. You are going there to get your first meal after quarantine and the meal cost $35.
sveta [45]

Answer:

You will be paying $41.30 in total.

Step-by-step explanation:

The cost of the meal is $35 and you want to leave 18% tip on the meal.

We want to find the total amount that will be paid.

First, we have to find 18% of $35 and then, add it to the original bill ($35).

18% of 35 is:

18/100 * 35 = $6.30

The tip is $6.30, therefore, the total amount paid will be:

$35 + $6.30 = $41.30

You will be paying $41.30 in total.

what do i write for this " Write a problem that requires adding 1 to the quotient when interpreting the remainder."
Mariana [72]
You should write a ( real world situation ) question that can only have whole numbers as a solution because you would divide and then you can not have a fraction left over so instead you add one. For instance there are 132 students going on a field trip. 20 students can fit on each bus. how many buses are needed? 7 because when you divide 132 by 20 you get 6 remainder 12. You can not just make 12 students walk to the location so you would add an extra bus.

PLEASE HELP MEEEEEE PLEASEEEEEEEE!!!!!! IM TIMED

Set up an equation to solve.

$8.50x (since it is the rate of change) + $12 (flat fee) = total money earned (or y). In this case, we have the total, amount, and are looking for x. Plug $139.50 into the equation.

$8.50x + $12 = $139.50

Now, solve for x.

$8.50x + $12-12 = $139.50-12  > <em>$8.50x = $127.5</em>

$8.50/8.50x = $127.5/8.50 > <em>x = 15</em>

So, the correct answer is <u>D. Olivia babysat for 15 hours.</u>
