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)=(y)/(x)

\Rightarrow\ k=(3)/(2)=1.5

\Rightarrow\ k=(7)/(4)=1.45

⇒ k is not a constant of proportionality.

⇒ the variables x and y are not proportional.
The answer is:Not proportional

Can 1/2 be written as a terminating decimal?

Answers

Yes it can and the answer would be 0.5

Terminating decimals are numbers that never stop going after the period. Such an example would be 10/3 which would give 3.333333 indefinitely. 1/2 gives a whole number, that is, 0.5

Solve for x. Express the answer in simplest form,

Answers

(6x-1)/(5)=(3)/(1) \ \ \ |\hbox{cross multiply} \n6x-1=3 * 5 \n6x-1=15 \n6x=15+1 \n6x=16 \nx=(16)/(6) \nx=(8)/(3) \nx=2(2)/(3)
In order to solve for x, you need to isolate the x on one side.  First, you need to multiply the 5 onto the other side to get rid of the fraction.  Then, just add 1 and divide by 6 to isolate the x (steps will be shown below):

(6x-1)/(5)=(3)/(1)\n5((6x-1)/(5))=5(3)\n6x-1=15\n6x-1+1=15+1\n6x=16\n6x/6=16/6\nx=(16)/(6)=(8)/(3)

So, x = 8/3
