Answer:
The expression representing the sum of three times a number and six, over the difference of seven times that number and nine
Step-by-step explanation:
we have

Let
p -----> the variable
we understand that
In the numerator we have (3p+6)
The statement that corresponds to this algebraic representation is "The sum of three times a number plus six"
The denominator is (7p-9)
The statement that corresponds to this algebraic representation is "The difference of seven times the number and nine"
therefore
The statement that represents this problem is "The sum of three times a number and six, divided by the difference of seven times the number and nine"
In total, there are 10 trucks and 18 tractors. I arrived at this by multiplying 10 by 1.8, which equals 18. Adding the number of trucks and tractors gives a total of 28.
