Answer:
500
Step-by-step explanation:
that is the procedure above
2(x+6)=x(x+1)
2x+12=x^2+x
x^2-x-12=0
(x-4)(x+3)=0
x-4=0
x=4
x+3=0
x=-3
For this specific equation the answer is x - 2
This math problem does not have a formula so we have to make one through analysis.
Here are the given details:
Money Per Page = $3.50/page
Job = 500 pages
Words Per Page = 250 words
Jim's Performance = 80 words/minute
Find:
Money Earned In Total = ?
Work Hour = ?
Here are the formula formulated through analysis:
Money Earned in Total = Money Per Page × Job
Work Hour = Job ÷ Jim's Performance
Solution:
Money Earned in Total = $3.50/page × 500 pages ; Multiply the numbers but cancel out the unit 'page'
Money Earned in Total = $1,750.00
Now, let's find the Work Hour:
Work Hour = 500 pages ÷ 80 words/minute ; in this case, we need to convert 500 pages to the total number of words all in all.
Conversion:
if 1 page = 250 words/page, therefore it is going to be:
500 pages × 250 words/page = 125,000 words ; we did this in order to have the unit 'page' to be cancelled out.
Now, let's substitute it.
Work Hour = 125,000 words ÷ 80 words/minute ; in this case, you can now cancel out the unit 'word'
Work Hour = 1,562.5 minutes ; since we are looking for hour, we need to convert it.
Conversion:
If 1 hour = 60 minutes, there it should be:
1,562.5 minutes ÷ 60 minutes/hour = 26.042 hours ; cancel out the unit 'minute'.
FINAL ANSWERS:
Money Earned in Total = $1,750.00
Work Hour = 26.042 hours
You would need to add 0.25 from t to get the number of hours ( this would be the total number of hours she has raced) and then multiply that by her speed.
The equation would be d = 35(t+0.25)
