Answer:
Step-by-step explanation:
20. First find the values of the numbers being added.
These numbers have a common denominator, so you can add the numerators
27 + 25 = 52
so the number comes out to
to simplify, divide the numerator and denominator by 4.
So the final fraction becomes
However the question doesn't have this answer and now I am confused. I assumed that the expression was but the picture is a little bit blurry and I have bad eyesight so let me know if it is not. I'm too tired to delete this so next problem.
21.
4x + 8x + 7 + 4
Combine the like terms to get the expression
12x + 11 the answer is c.
Answer:

Step-by-step explanation:
Given that the number of purses a vendor sells daily has the probability distribution represented in the table.
Expected Value,
Therefore:
If each purse sells for $50.00, the number of expected daily total dollar amount taken in by the vendor from the sale of purses
=Expected Value X $50
=1.62 X $50
=$81
The correct option is D.
Answer: (27, 9)
Multiply the original coordinates by the scale factor 3 to get this answer
9*3 = 27
3*3 = 9
This only works if the center of dilation is the origin.
The general rule is where k is the scale factor.
