Answer:
Mendez got 989 votes
Mendez secured 23% of the votes.
Step-by-step explanation:
Please refer to the attached circle graph,
The circle graph summarizes the votes secured by 6 candidates.
The central angle for the Mendez slice is 82.8° and the whole circle is 360°.
There are total 4300 votes and we want to find out the percentage of the votes secured by Mendez.
Let X be the number of votes that Mendez got.
So Mendez got 989 votes.
Let us now find out the percentage of votes
Therefore, Mendez secured 23% of the votes.
Answer:
3x^2 + 3xy/2 - 7xy^2/2
Step-by-step explanation:
So we know the perimeter is 20x^2 + xy - 7y^2,
To find any perimeter you need 2l + 2w = P so,
One of the sides is 7x^2 - xy
First plug in the values,
2(7x^2-xy) + 2w = 20x^2 + xy - 7y^2
Multiply,
14x^2-2xy + 2w = 20x^2 + xy - 7y^2
Subtract,
14x^2 - 2xy - 14x^2 + 2xy + 2w = 20x^2 + xy - 7y^2 - 14x^2 + 2xy
2w = 6x^2 + 3xy - 7y^2
w = 3x^2 + 3xy/2 - 7xy^2/2
Answer:
(5a+4c)(2a-b)
Explanation:
Given the expression:
First, group the expression into two:
• In the first group, 5a is a common factor.
,
• In the second group, 4c is a common factor.
Factor these out by dividing each term by the GCF of each group.
Since the terms inside the brackets are the same, combine:
