Answer: The x and y represents the number of bought apples and bananas respectively. The coefficients represents the cost of each apple and banana.
Explanation:
It is given that at a local grocery store apples cost $0.50 each and bananas cost $0.30 each. the expression 0.50x+0.30y can be used to find the cost of buying some apples and bananas.
Let the number of apple purchased be x and number of banana purchased be y.
The cost of each apple is $0.50. So, the cost of purchased apple is 0.50x.
The cost of each apple is $0.30. So, the cost of purchased apple is 0.30y.
The total cost is the sum of cost of apples and cost of bananas.
It is same as the given equation.
So, the x and y represents the number of purchased apples and bananas respectively. The coefficients represents the cost of each apple and banana.

Answer:
Step-by-step explanation:
1). Geometric mean of a and b =
Therefore, geometric mean of 2 and 50 =
= 10
2). By geometric mean theorem,
e² = 6 × 24
e = √144
e = 12
Similarly,
d² = 6 × 30
d = √180
d = 6√5
And
c² = 30 × 24
c = √720
c = 12√5
