Your variable is r for the number of rooms
So your equation is 395= 35*r + 80
First subtract 80 from both sides of the equation
315 = 35r
Next divide 35 from both sides of the equation
And your final answer is 9 rooms in total he sprayed.
Total cost = 35(#ofrooms) + 80
The answer is (1, -2)
because f(x) = y
so, where y is -2 , x is 1

Step-by-step explanation:
The distance between A to B is 1 unit
Lan wants to run less than 7/12 miles. It says to find out a fraction with a denominator of 4 and which is less than 7/12.
Let's assume the required fraction to be x/4 such that x/4 is less than 7/12.
So we must have multiples of 3's that should be less than 7, we have only two choices 3 < 7 or 6 < 7.
It means x = 1 or x = 2, and the required fraction would be 1/4 or 2/4.
2/4 is simplified to 1/2 and the question says to have denominator 4.
Hence, final answer is 1/4
