Final answer:
The equation relating the number of novels Joe needs to read (n) to the months (m) is n = 2m. For 19 months, Joe needs to read 38 novels.
Step-by-step explanation:
The student asked to write an equation relating the number of novels Joe needs to read (n) to the number of months (m) given that Joe reads 2 novels each month.
The equation representing this relationship is n = 2m.
Using this equation to find the number of novels Joe needs to read in 19 months, we substitute the value of m with 19: n = 2 × 19.
Therefore, Joe needs to read n = 38 novels in 19 months.
Let n be the number of novels Joe needs to read in m months. Write an equation relating n to m. Then use this equation to find the number of novels Joe needs to read in 19 months (Joe reads 2 novels each month).
