19.98 rounded to the nearest whole number is 20. In the number 19, 9 round the 1 to a 2 and the 9 becomes a 0 because of the 9 behind the decimal. OR You could think of a percent being 100. 98 is only 2 numbers away from 100 and thus you can round 19 up to 20.
Hope this helps! (:
The answer is 20. To make problems like this easier for you to understand, if the number is greater than 5 round up. If the number is 4 or less, round down. I hope you get what I am saying.
When using elimination to solve 2x-3y = 4 7x+ 6y = -1 what would be a possible first step? A 4x – 6y = 8 7x + 6y = -l B x = 3/2y + 2 7x + 6y = -1 C 2x -3y = 4 x = -6/7y – 1/7 D y = 2/3x – 4/3 7x + 6y = -1
Answers
A because you have to multiply the problems to even in out (2x-3y=4) x2 (7x+6y=-1) x1
4x – 6y = 8 7x + 6y = -l
joseph had a quarter of a cookie. ellen had a half of a different cookie. The peice joseph had was larger. how could ellens peice be smaller? explain.
Answers
My theory is the cookie could be smaller because Ellen's cookie might have been smaller as a full than Joseph's.
For example, Joseph's cookie may have 24 pieces, while Ellen's cookie may have been 4 pieces.
The Cookie that joseph was eating was larger. Half of a small cookie is smaller than a quarter of a larger cookie.
