40= 1,2,4,5,8,10,20,40
48= 1,2,3,4,6,8,12,16,24,48
the gcf is 8.
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:
0.3
Step-by-step explanation:
x is the number to be added to 0.7 to have a sum of 1.



An estimate helps you place the decimal point because when you place 3.7 and 5.1 to multiply you have to count how many spaces of numbers there are. So the answer is 18.87.
I confirm with the answer that k is the slope of the graph<span>. If the variables x and y vary directly when x = 3 and y = 15, then: a. Write an equation that relates x and y.</span>
