Let's assume the number of concert ticket stubs Domingo has is "x."
According to the problem, Ruth has 2 times as many concert ticket stubs as Domingo, which means Ruth has 2x concert ticket stubs.
Since they have a total of 138 concert ticket stubs together, the equation would be:
x + 2x = 138
Combining like terms:
3x = 138
Dividing both sides of the equation by 3:
x = 138/3
x = 46
So, Domingo has 46 concert ticket stubs.
And Ruth has 2x concert ticket stubs:
2 * 46 = 92
Therefore, Ruth has 92 concert ticket stubs.
To find out how many concert ticket stubs Ruth has, we need to set up an equation based on the information given.
Let's assume that Domingo has x concert ticket stubs.
According to the given information, Ruth has 2 times as many concert ticket stubs as Domingo. Therefore, Ruth has 2x concert ticket stubs.
The total number of concert ticket stubs they have together is 138. So we can set up the equation:
x + 2x = 138
Combining like terms, we get:
3x = 138
Now, we can solve for x by dividing both sides of the equation by 3:
3x/3 = 138/3
x = 46
So, Domingo has 46 concert ticket stubs.
To find out how many concert ticket stubs Ruth has, we can substitute the value of x into the equation:
2x = 2 * 46
2x = 92
Therefore, Ruth has 92 concert ticket stubs.
To summarize:
Ruth has 92 concert ticket stubs.
Domingo has 46 concert ticket stubs.
