Answer:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Answer:
16
Step-by-step explanation:
To solve this equation you need to do the opposite to factor everything out. Since the 6 is being multiplied you need to divide it by 6 and whatever you do to one side you do to the other:
48=1/2b(6)
6÷6=1
48÷6=8
8=1/2b
Multiplying by 1/2 is the same as dividing by 2. So what we want to do is multiply by 2:
8=1/2b
1/2×2=1
8×2=16
16=b meaning you base is 16
To check your answer you can put 16 in as b
48=1/2(16)6
48=1/2(96)
Remember multiplying by 1/2 is the same as dividing by 2:
48=48
