The temperature is 47° F. It gets warmer by x degrees and reaches to 52° F. Find x.
eqautiion included
47 + x = 52
Subtracting 47 from both sides:
x = 5
Therefore, the temperature gets warmer by 5 degrees.
There are 9 red and blue marbles, among which x are red. How many are red? Denote blue marbles as y.
eqautiion included
x + y = 9
Since x represents the number of red marbles, the answer is x.
i need x= a number
If the total number of marbles is 9, and x represents the number of red marbles, then the number of blue marbles can be represented as:
y = 9 - x
So, if we know the value of x, we can calculate y as well.
For example, if x = 4, then:
y = 9 - x = 9 - 4 = 5
Therefore, there are 4 red marbles and 5 blue marbles.
wait first answer was right but i put x=x nd it wrong but eqyation right
I apologize for the confusion. You are correct, the equation is correct and gives us the answer to the problem:
x + y = 9
Since the problem asks for the number of red marbles (represented by x), we can solve for x by using the equation above. Here's how:
x + y = 9
y = 9 - x (subtracting x from both sides)
Now we can substitute the equation for y back into the original equation:
x + (9 - x) = 9
Simplifying:
x + 9 - x = 9
9 = 9
Since this is a true statement, we know that the equation is consistent, and we have found a possible solution: x can be any number between 0 and 9 as long as y is the difference, or 9 - x.
what x=? ur not helping
I apologize for any confusion.
To find x, we need more information or context. The equation x + y = 9 represents a relationship between x and y, but it does not provide enough information to find the value of x unless we have another equation or some additional information.
For example, if we know that all marbles are either red or blue, and there are twice as many blue marbles as there are red marbles, then we can set up a second equation:
y = 2x
Now we can substitute y = 2x into the first equation to get:
x + 2x = 9
Simplifying:
3x = 9
x = 3
Therefore, there are 3 red marbles and 6 blue marbles.
I hope this helps. Let me know if you have any further questions.
