How to solve a linear simultaneous equation using Canon F-715SG?

1. Debra use http://www.webmath.com/equline1.html
   You want to find the equation for a line that passes through the two points:
   (4,3) and (1,5).
   put these into
   http://www.webmath.com/equline1.html
   and it will explain the maths involved
   is
   from http://www.webmath.com/equline1.html
   y=-2/3x+17/3
   midpoint M so x increased 3 from point k so at point JK would have to have x as 7
   y=2/3*7+17/3
   y=14/3+17/3
   y=31/3
   y=10.3
   point J should be 7,10.333333333333333333333333334
   or 7, 10 and 1/3

Solution = 1.33 + 2.25 = 3.58 or 3 37/64

810 divided 9= 90

A class consists of 16 kids, 6 boys and 10 girls.
Emily questioned all the students and discovered that
8 out of 10 girls prefer valentines day over birthdays, but only 2 out of 6 boys prefer valentines day over birthdays.
What is the ratio of children in the class that prefer valentines day over birthdays.

Sorry we are not a math solving website, we deal in product self repair and use of said products.

Oh wow, lots of math going on here...

There are 4840 square yards in an acre and 9 square feet in a square yard (4840 x 9 = 43,560).

An acre is an old timers measurement used in agriculture...
it was 4 poles wide and 40 poles long. A pole is equivalent to sixteen and a half feet. So back then, an acre was a piece of farming land 660 feet long (220 yards or one eighth of a mile) and 66 feet wide (22 yards or one eightieth of a mile).

Acre is a measure of area, which would be square feet.

Feet are a measure of distance.

The best you could do is something like this:
An acre is 43, 560 square feet.
Draw/imagine a square or a rectangle that would cover that much area.

If it is a square, it would be (approximately) 208.7 feet on each side.

Its perimeter (the distance around it if you walk an imaginary fence around you acre-sized plot) would be 834.8 feet.

Trying to to figure out an acre of 'Circle' - hmmmmm???

Radius = 1/2 of Diameter

sorry, just can't wrap my head around this to come up with the correct equation.
maybe we can get lucky with some other brainiac taking what I did provide and come up with a solution for you?

Square - It would be 208.7 feet across if you walk across it, and the same if you walk the other way across it.

The correct answer is 7,000. I hope I helped!
