You should use curly braces instead of parenthesis to indicate set notation. The answer is {101, 404} as these two values are in both set A and set B at the same time. The upside down U symbol means "intersection" which is where the two sets overlap. In terms of a Venn Diagram, you'll have two overlapping circles. In the overlapping region is where 101 and 404 are written. In the region of circle A that is outside of B, you'll have 202, 303, and 505. There is nothing to write in the region of B that is outside of A (since all of B is inside A)
Once again, the answer is {101, 404}
Answer:
55 paper plates for $4.40 is your best buy because the price for unit is $0.08
Step-by-step explanation:
First find the price for unit of each option
we have :
85 paper plates for $8.08
55 paper plates for $4.40
To find the price per unit we divide 8.08 ÷85 = .09 rounded to the nearest cent is .10
and 4.40 ÷ 55 = .08
Therefore, the best buy is $.08 or 55 paper plates for $4.40
The idea is to group up the terms into two groups, factor each group and then factor out the overall GCF
2x - 18 + xy - 9y
(2x - 18) + (xy - 9y)
2(x - 9) + (xy - 9y)
2(x - 9) + y(x - 9)
(2 + y)(x - 9)
(x - 9)(2 + y)
Answer: Choice B
Answer:
5w2
Step-by-step explanation:
(5w2 ^2/2)
Simplify (do 2^2)
= 5w4/2
Divide by 2
= 5w2
