170? I think. I don't really understand your question
Alright, lets gets tarted.
Suppose there are x rows of tomato plants Krystyn make.
Again suppose there are n plants in each row.
We could find total plants by multiplying number of plants in each row with number of rows.
Hence total number of plants will be = 
But as per question, total number of plants are 54. It means

Now, the number of plants in each row was 3 more than the number of rows means

Putting this value of n in first equation we made


Subtracting 54 in both sides


Factoring

Means x = 6 or x = -9
The number of rows can not be negaive.
Hence x = 6
It means number of rows of tomato plants will be 6. : Answer
Hope it will help :).
Answer:
20
Step-by-step explanation:
Number of paperback books = 4
Percentage of total books that were paperbacks = 20%
Let total number of books = x
Hence,
20% of total books = paperback books
20% of x = 4
0.2 * x = 4
0.2x = 4
0.2x / 0.2 = 4 / 0.2
x = 20
Total number of books = 20
