Answer:
Step-by-step explanation:
Elvin and Carol together have Rs. 84. If Elvin gives Carol Rs. 32, then Carol will have twice as much money as Elvin. How much money, do Elvin and Carol have originally?
Let the amount of Elvin has originally = E
Let the amount of money Carol has originally be = C
E + C= Rs. 84
E + C = 84 ......Equation 1
If Elvin gives Carol Rs. 32, then Carol will have twice as much money as Elvin.
C + 32 = 2E
C = 2E - 32
We substitute into Equation 1
E + C = 84 ......Equation 1
E + 2E - 32 = 84
3E = 84 + 32
3E = 116
E = 116/3
E =

The numeric value of the composite function at x = 2 is given as follows:
(f ∘ g)(2) = 33.
<h3>Composite function</h3>
The composite function of f(x) and g(x) is given by the rule presented as follows:
(f ∘ g)(x) = f(g(x)).
It means that the output of the inside function serves as the input for the outside function.
In the context of this problem, the functions are given as follows:
The composite function is:
(f ∘ g)(x) = f(-2x) = (-2x)² - 3(-2x) + 5 = 4x² + 6x + 5.
At x = 2, the numeric value is given as follows:
(f ∘ g)(2) = 4(2)² + 6(2) + 5 = 33.

Answer:
See below.
Step-by-step explanation:
Total consumed = 1/4 + 1/5
= 5/20 + 4/20
= 9/20 of the salad they eat
1 - 9/20
= 11/20 of the salad is left
10/20 is half so more than half the salad is left
