Answer:
if your solving for n.....
Step-by-step explanation:
n=3
Steps
I’m using elimination so I’m trying to get rid of y
To do that I multiply the first equation by 2 and the second by -3. Then solve
4x + 6x = 12
15x + -6x = -12
—————————
19x + 0 = 0
Divid by 19 to get x to one side. 0/19 is 0 so
X= 0
Plug that into an equation so 0 + 3y = 6
Divid by 3 and y = 2
Answer x = 0 y = 2
Answer:
1) 24x-72; 2) 6x-18; 3) 2x-9
Step-by-step explanation:
You can divide it or multiply it by whatever number it is to make it a whole number, not a decimal. Or else it will be even more difficult.
Number of candles =(total volumes used by the company)/(volume of one candle)
volume of one candle =5cm*2cm*12cm=120cm^3
hence number of candles =5040/120
, ,=42candles
