Answer:

Your equation option is possibly in here somewhere.

Step-by-step explanation:

A = <em>C - 2</em>

B = A + 6  → A = <u>B - 6 </u>

<em>C - 2</em> = A = <u>B - 6</u> → B = <u><em>C + 4</em></u>

44 = C + B + A

44 = C + (<u><em>C + 4</em></u>) + (<em>C - 2</em>)

44 = 3C + 2

42 = 3C

C = 7

Answer:

(A) Your friend will save $282.

(B) Your friend will get 23.5% off the original price of the mattress.

Step-by-step explanation:

We first need to find out the price of the mattress after the 15% discount. Our first step is to find what 15% of 1,200 is. We can do this by multiplying the two numbers.

1,200 x 15% -----> 1,200 x 0.15= 180.

15% of $1,200 is $180.

Next subtract $180 from $1,200, which equals $1,020. We can now apply the 10% off internet coupon.

1,020 x 10% ------> 1,020 x 0.10= 102.

10% of $1,020 is $102.

Next we subtract $102 from $1,020 and we get $918, the final price of the discounted mattress.

We subtract to see how much money the friend saved.

$1,200 - $918= $282.

We can get the percentage by dividing $282 by $1,200.

282 / 1200= 0.235 decimal form ----> 23.5%

mojhsa [17]

Answer: 1,250

Step-by-step explanation:

Given: The total number of students in the school= 25,000

Since each class has 10 students , therefore, the number of classes in the school= \frac{25000}{10}=2500

Also, Each student takes 2 classes a day, thus the number of classes taken by total teachers in a day = 2\times2500=5000

Also, each teacher teaches 4 classes.

Then the number of teachers in the school =\frac{5000}{4}=1250

Hence, the number of teachers are at  Big Big School = 1,250

s2008m [1.1K]

Hi!

<h3>To find the prime factorization of a number, keep dividing by the smallest factor that goes into it. </h3>

63/3 = 21

21/3 = 7

7/7 = 1

<u>3 · 3 · 7 = 63</u>

<h2>The answer is D. 3 · 3 · 7 </h2>

Hope this helps! :)
