The height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. When graphed,
the function gives a line with a slope of -0.6. See the figure below. Suppose that the height of the candle after 12 hours is 17.8 centimeters. What will be the height of the candle after 19 hours?
No he walks 7/10 of a mile you have to make 2/5 have a common denominator with 3/10 so 2×2=4 (numerator) 2×5=10 (denominator) 4/10+3/10= 7/10 since you only add the numerator because the denominator makes it a like term
