Answer: 2 sticks.
Step-by-step explanation:
Given statement: You need 3 sticks of butter for every 24 cookies you bake.
Using unitary method , the number of sticks of butter used to bake 1 cookie=
Then the number of sticks of butter used to bake 1 cookie=
Hence, the number of sticks of butter used to bake 16 cookies= 2
Answer: 30 pounds of coffee beans worth $10.50 per pound was used.
20 pounds of coffee beans worth $13.00 per pound was used.
Step-by-step explanation:
Let x represent the number of coffee beans worth $10.50 per pound that should be mixed.
Let y represent the number of coffee beans worth $13.00 per pound that should be mixed.
50 pounds of beans worth $11.50 per pound is to be made. The total cost of the mixture would be
50 × 11.5 = 575
This means that
10.5x + 13y = 575 - - - - - - - 1
The total number of pounds of each type of coffee used is 50. This means that
x + y = 50
Substituting x = 50 - y into equation 1, it becomes.
10.5(50 - y) + 13y = 575
525 - 10.5y + 13y = 575
- 10.5y + 13y = 575 - 525
2.5y = 50
y = 50/2.5 = 20
x = 50 - 20= 30

Answer:
The equation is not a function.
Step-by-step explanation:
We are given that
Function: It is mapping between the values of two sets A and B.
Each element of A has unique value in set B.
By definition of function
In given function
y has no unique value for each value of x.
Substitute x=0
Hence, it is not a function.
