My answer: 375 pages
Reasoning: Well if it took 20mins to print 250 pages then divide both in half. 10mins to print out 125 pages. Then multiply both by 3. 30mins to print out 375 pages
Answer:
- 15 = -3c +12
- -3n +8 = -7
- 5z -40 = 10
- 3.4s -35 = 50
Step-by-step explanation:
Usually, you're asked to "simplify" an equation, meaning that you eliminate parentheses and combine like terms. Asking for "simplest form" suggests something different. The simplest form is the form that has the variable equal to a constant--the solution, in other words.
We suspect you want the <em>simplified form</em>, but since you asked for the <em>simplest form</em>, that is here, too.

1. 15=-3(c-1)+9
15 = -3c +3 +9
15 = -3c +12 . . . . . simplified form of the given equation
-1 = c . . . . . . . . . . "simplest" form

Step-by-step explanation:
Direct variation is essentially a linear equation, where there is a constant rate. Direct variation can be applied to many things, and we can use it to represent how much money someone has in their bank account after "x" weeks if they're depositing a constant amount of money each week.
So a practical example would be: If someone just opened a bank account and deposits $50 every week, how many weeks will it take for them to have $400 in their account.
So the slope is given in the question, it's $50, since their depositing that constant amount each week. So this gives us the equation: 
where x represents the amount of weeks. The y represents the amount of money they have, and since we want to find when this equals 400, we set the y=400, and then solve for x. This gives us the equation: 
. Dividing both sides by 50 you get: 
. So it'll take 8 weeks to have $400 dollars, if you deposit 50 dollars each week.
I have no "real" answer, because the river may curve...
Fun answer: farmer Ed clearly does not realize you can Not create a rectangular plot that borders a river unless it is artificial and instead of dirt, it would Need to be concrete to ensure a constant straight edge; although even in that case, it would no longer Be a river! It would be a mote or channel. So this problem is unsolvable at his current standards.
It can be 1/3, 1/7, 2/7, 3/7, 1/5, 2/5, 1/13, 2/13, 3/13, 4/13, etc
