y 3 7 11 15
Answer choices:
1/3
not proportional
3/2
1
Answer: not proportional
Step-by-step explanation:
The constant is called the coefficient of proportionality if one variable is always the product of the other variable and a constant. And the variables are said to be directly proportional.
In the given table , let the variables are proportional then the constant of proportion(k)=
=1.5
=1.45
⇒ k is not a constant of proportionality.
⇒ the variables x and y are not proportional.
Something times 2 equals 36
now let say that X is the number missing
Replace x by something
x*2-36
2x=36
Divide both sides by 2
x= 18
I hope that's help :)
another way you can do that is to divide 36 by 2 and it will be 18
I hope that's help and if you have questions please ask ;)
