50 is the answer.
We know that 60% is equal to 0.60. We don’t need to write the extra 0 in the end, so we can just write 0.6
. So, the question is saying that 30 is 0.6 of the total number of marbles. This means that 30 is 0.6 times the total number of marbles.
To write this in equation form, I will use x to represent the total number of marbles:
30=0.6x
Now, we need to solve for x.
On one side of the equation we have only x, and in the other side we only have a number.
So, to solve it, we need to divide both sides of the equation by the coefficient on x, which is 0.6.
30/0.6 = 0.6/0.6x
Solve:
30/0.6 = x
x = 50
The answer is 50.

Answer:
4.95m
Step-by-step explanation:
Let the length of longer and shorter pipe be x and y respectively..
given,
x/y=9/2...(i)
x-1.65=3y ...(ii)
in eqn ii..
x-1.65=3y
or, x/y - 1.65/y = 3
or, 9/2-1.65/y =3
or, 4.5-3 = 1.65/y
or, y=1.65/1.5
•°• y = 1.1m
now,
x/y = 9/2
or, x/1.1 = 4.5
x= 4.5×1.1
•°• x= 4.95m
thus, the length of the longer pipe is 4.95m
<u>Answer:</u>
The correct answer option is B. both a function and a relation.
<u>Step-by-step explanation:</u>
We are given a from from which we can see that for each input we have exactly one output.
This means that we have a function because each element in the domain is matched with exactly one element in the range.
It is also a relation since each input related to the out put in some way.
Therefore, the correct answer option is B. both a function and a relation,
There are a lot of ways you can do this, depending on what numbers you use, you can divide, multiply, add, or subtract to get 4,384, did you mean a specific term of math?<span />
