+ The volume of each candle is : 6*5*14= 420 cm³
+ The company used 4620 m³, so we have 4620:420= 11 candles
That is for you, 11 candles
So
C=10
3c+c/2c means
3(10)+10/2(10)
30+10/20
40/20=2
The number is the second one
To do this you need to work backwards. if you note the number as 'n' you can put
7n = 5600
to find n you simply divide both sides by 7 getting
n = 5600/7
n = 800
For this case, the first thing we must do is define variables.
m: number of times you cut the grass
d: amount of dollars you earn.
We now write the linear equation that models the problem:
d = 12m
The slope of the line is 12, which means that each time you cut the grass, you earn 12 dollars.
Answer:
an equation for the number of dollars, d, you earn when you mow the lawn m times is:
d = 12m
