.<br> Round 12.5829 to the nearest hundredth. Rounded number = ___
Savatey [412]
The hundredth's place is the second number after the decimal. In order to round to such place, you look at the number after it. For example, the number in the hundredth's place in 47.9025 is 0. In order to round, you must look at the number after it, in this case 2. Since 2 is less than 5, the 0 will not be rounded up and remain 0. The answer to your particular question is 12.58.

3 bags and 4 pens together cost 950 dollars whereas 4 bags and 3 pens cost 1150 dollars write two simultaneous equations
Flauer [41]
-----------------------------------------------------------------------------------------
Given information
-----------------------------------------------------------------------------------------
3 bags + 4 pens = $950
4 bags + 3 pens = $1150

-----------------------------------------------------------------------------------------
Form the 2 equations
-----------------------------------------------------------------------------------------
Let x be the cost of 1 bag.
Let y be the cos of 1 pen.

3x + 4y = 950
4x + 3y = 1150

-----------------------------------------------------------------------------------------
Solve for x and y
-----------------------------------------------------------------------------------------
3x + 4y = 950  -------------- (1)
4x + 3y = 1150 ------------- (2)

----------------------------------------------------------------------------------------
Equation (1) x 4
----------------------------------------------------------------------------------------
12x + 16y = 3800 ------------- (1a)

----------------------------------------------------------------------------------------
Equation (2) x 3
----------------------------------------------------------------------------------------
12x + 9y = 3450  ------------- (2a)

----------------------------------------------------------------------------------------
Equation (1a) - (2a)
----------------------------------------------------------------------------------------
 (12x + 16y) - (12x + 9y) = 3800 - 3450
7y = 350
y = 350 ÷ 7
y = 50 

----------------------------------------------------------------------------------------
Substitute y = 50 into equation (1)
----------------------------------------------------------------------------------------
3x + 4 (50)  = 950
3x + 200 = 950
3x = 950 - 200
3x = 750
x = 250

----------------------------------------------------------------------------------------
Find cost of a bag and a pen
----------------------------------------------------------------------------------------
Bag  = x = $250
Pen = y = $50

----------------------------------------------------------------------------------------
Answer: The bag cost $250 and the pen cost $50
