The answer is 1.25 hours.
STEP 1.
Each page has about 350 words: 1 page - 350 words
15 pages is x words: 15 pages - x words
1 : 350 = 15 : x
x = 15 * 350 : 1 = 5250
So, she has to type at least 5250 words.
STEP 2:
<span>Stephanie can type around 70 words per minute: 70 words - 1 minute
x words in 1 hour = 60 minute: x words - 60 minute
70 : 1 = x : 60
x = 70 * 60 : 1 = 4200
So, she types around 4200 words per hour.
STEP 3:
Now we have:
</span>- she has to type at least 5250 words
- she types around 4200 words per hour
5250 : x = 4200 : 1
x = 5250 * 1 : 4200 = 1.25 hours

Answer:
<em>There are 12 boys and 18 girls</em>
Step-by-step explanation:
<u>Equations</u>
There are 30 students in a class. Let's call:
x = number of boys
Since the sum of boys and girls is 30:
30 - x = number of girls
The ratio of boys to girls is 2:3, thus:
Crossing denominators:
3x = 2(30 - x)
Operating the parentheses:
3x = 60 - 2x
Adding 2x:
5x = 60
Dividing by 5:
x = 60/5 = 12
x = 12
There are 12 boys and 30-12=18 girls
