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.
18000 dollars invested with 5% interest.
=> 18 000 dollars * 0.05 = 900 dollars for annual interest rate.
Now, how much interest will he be earning in 3 years?
=> first year = 18 900 dollars * .05 = 945 dollars for the 2nd year
=> 2nd year = 18 900 dollars + 945 = 19 845 dollars
19845 * .05 = 992.25
=> 3rd years = 19845 + 992.25 = 20837.25 total amount he will get back.
For interest = 900 + 945 + 992.25 = <span>$2837.25</span>
The value of 2 in 2,783 is thousand. The value of 2 in 7,283, is hundred.
So it is one times the value.
STEP 1:
Tally up the total number of batches.
= 3 batches + 4 batches
= 7 batches
STEP 2:
Multiply the total number of batches by the amount of butter used in one batch (which is 1/4 cup).
= 7 batches * 1/4 cup per batch
= 7 * 1/4
= (7*1)/4
= 7/4
= 1 3/4 cup of butter
Beth used 1 3/4 cup of butter to make a total of 7 batches of cookies.
Hope this helps! :)
