Answer:a valid solution is (1,3)
Explanation:First, let' simplify the given equation:
14mn = 55 - 7m - 2n
14mn + 2n = 55 - 7m - 2n + 2n
n (14m + 2) = 55 - 7m
n =
Now, we have only one equation in two unknowns. Therefore, the only way to solve this is by assuming one of the variables and solving for the other taking into consideration that both should be positive integers.
1- Assume m = 2:
n =
.....> n is not a positive integer .........> This assumption is rejected
2- Assume m = 1:
n =
.......> both m and n are positive integers ........> This assumption is accepted ...........> Therefore, the solution would be (1,3)
Hope this helps :)
Answer:
The approximate number of gallons consumed by a person in 2010 will be 4.9 gallons
Step-by-step explanation:
Recall that the formula for exponential decrease is given by a function of the form:
where A is the initial value, r is the rate of decrease, and x is the time elapsed.
In our case, the initial value of gallons of juice per person (at the starting time = 1981) is 16.5 gallons. So A = 16.5 gallons.
the rate of decrease "r" is the decimal form of: 4.1%, that is r = 0.041
So we have:
Now we can calculate what the average number of gallons would be in the year 2010, knowing that between 1981 and 2010 there is an elapsed time in years of: 2010-1981 = 29 years. Then:
