Jamie's age is n. (given)
Brian's age is 2n. (given)
Half of Brian and Jamie's present age is (n +2n)/2 = 3n/2.
Let m represent Morgan's age now. Then
... m + 8 = 2 + 3n/2 . . . . . in 8 years, Morgan's age will be 2 more than ...
Subtract 8 to find Morgan's present age:
... m = 3n/2 - 6 . . . . Morgan's present age

Answer:
The correct answer is $0,56.
Step-by-step explanation:
In order to begin with the calculation we must understand the information we have.
We know that Lanny bought 1.4 pounds of rice, for a single pound of rice she paid $ 0.40.
To find out how much you paid in total for the rice, we simply multiply the value of the unit 0.40 by the total value of pounds of rice 1.4.
So:
0.40 x 1.4 = 0.56
In this way we can verify that the total Lanny paid for the rice was $ 0.56.
Answer:
f(g(x)) = g(f(x)) = x
Step-by-step explanation:
Lemma;
If f(x) and g(x) are inverses, then the compositions f(g(x)) = g(f(x)) = x
