No, She is not correct.
Step-by-step explanation:
To find the greatest common factor of the expression 20x + 100xy.
Given expression 20x + 100xy.
Let us factor the expression 20x + 100xy.
Now take the common factor in the expression 20x + 100xy.
The common factor is 20x.
So, 20x + 100xy = 20x( 1+ 5y)
But Claudia says that the greatest common factor is 20(x+5xy).
The GCF is wrong.
So, she is not correct.

Answer:
24 girls
7 boys plus 8 girls is 15. 45 students / 15 = 3. 3 x 8 girls is 24.
x = 3
3/2.25 = 4/x Cross multiply
3x = 2.25 * 4 Combine the right
3x = 9 Divide by 3
3x/3 = 9/3
