Answer: x=0.5 or 1/2
Step-by-step explanation:
2/4=1/2
C, d, and e is the answer
Answer:
we know that
16/4-----------> 8/2---------> 4/1
so
case 1)
64/16--------> 32/8-----> 16/4------> 8/2------> 4/1
the quantity (64/16) is proportional to 16/4
case 2)
6/1 is not 4/1
so
the quantity (6/1) is not proportional to 16/4
case 3)
5/1 is not 4/1
so
the quantity (5/1) is not proportional to 16/4
case 4)
48*12--------> 24/6-----> 12/3------> 4/1
the quantity (48/12) is proportional to 16/4
case 5)
4/1 is equal to 4/1
so
the quantity (4/1) is proportional to 16/4
Step-by-step explanation:
You have not provided the complete question (value of y at a certain value of x), therefore, I cannot give u a specific final answer. However, I can explain how to solve this problem and you can apply on the numbers you have.
y varies directly with x means that as x increases, y also increases and vice versa.
This can be represented by the following equation:
y = kx
where k is the constant of proportionality.
Solving this for k, we would find that:
k = y/x
Examples:
If we are given that y = 4 at x = 2, then:
k = y/x = 4/2 = 2
If we are given that y = 1 at x = 3, then:
k = y/x = 1/3
In general, if we are given that y = a at x = b, then:
k = a/b
Hope this helps :)
