Answer:
11 nickels, 15 dimes, 22 quarters
Step-by-step explanation:
number of nickels = x
number of dimes = x+4
number of quarters = 2x
- - - - - -
total of nickels = 5x cents
total of dimes = 10x + 40 cents
total of quarters = 50x cents
- - - - - -
755 = 5x + 10x + 40 + 50x
755 = 65x + 40
715 = 65x
x = 11
x+4 = 15
2x = 22
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
Combine like terms the solve. For example:
5x + 20x = 100
25x = 100
/25 = /25
x =4
