Answer:
A. 25
B. -25
Step-by-step explanation:
Create a proportion.
Since it takes 7 minutes to print 63 pages, and half an hour is 30 minutes, you create two ratios(unit per unit) and line up the units(minutes to minutes, pages to pages).

Now you cross multiply, 63 * 30 = 1890 and 7 * x = 7x.
So we have 1890 = 7x.
Then we divide both sides by seven.

270 = x, therefore you can print 270 pages in half an hour :)
Answer: 50
Step-by-step explanation: 42x12=504. 504-4=500. 500/10=50.
Answer:
0.485
Step-by-step explanation:
Each term is 0.019 more than the term before it.
Therefore to find the next term, we just need to add 0.019 to the last given term:
0.466 + 0.019 = 0.485
The next term is 0.485.
Hope this helped!
<span>Normally when they tell you interest rate they say per annum meaning the percent interest rate for a year.
But in this problem they seem to say John pays 12% for a 146 day loan.
So interest = P * r / 100 = 8400 * 12/100 = $1,008.00
Maturity value = Principal + Interest = 8400 + 1008 = $9,408.00</span>
