Answer:
x = 1/3 and x= -2
Step-by-step explanation:
-5+ and - square root 5^2 -4 times 3 times -2 which is all over 2 times 3
so square rooted 5^2-4 times 3 times -2 is 7 - -5 + and - 7 both over 2 times 3 is -5-7 divided by 2 times 3 and -5 plus 7 divided by 2 times 3 is 1/3 and -5-7 divided by 2 times 3 is -2 therefore leaving x as 1/3 and -2

What is a parallelogram?A parallelogram is a quadrilateral that has two pairs of parallel sides.
In a parallelogram, opposite sides and angles are equal.
The adjacent angles add up to 180 degrees.
We have,

D C
Now,
AO = OC
BO = DO
O is the midpoint of BD.
O =(m, n)
m = (8 + 3) / 2
m = 11/2
n = (1 + 4)/2
n = 5/2
O = (11/2, 5/2)
Now,
O is the midpoint of AC.
m = (x + 0)/2
11/2 = x/2
x = 11
n = (y + 2)/2
5/2 = (y + 2)/2
y + 2 = 5
y = 3
The coordinates of C.

= (11, 3)
Thus,
The coordinates of vertex C are (11, 3).

In the latest meet the boys cross county team scored 55 points.If there were five runners on the team and each runner finished one after another. What places did they each come in?
Answers
Answer:
Runner 1 = 9th place
Runner 2 = 10th place
Runner 3 = 11th place
Runner 4 = 12th place
Runner 5 = 13th place
Step-by-step explanation:
Given that:
Number of runners = 5
Total points scored = 55
Finishing spot for each runner (they finished one after the other)
Hence,
x, (x + 1), (x + 2), (x + 3), (x + 4)
x + x + 1 + x + 2 + x + 3 + x + 4 = 55
5x + 10 = 55
5x = 55 - 10
5x = 45
x = 9
Hence,
Runner 1 = 9th place
Runner 2 = 10th place
Runner 3 = 11th place
Runner 4 = 12th place
Runner 5 = 13th place

a store owner sells a mix that is 45% cashew nuts how many pounds of cashews should be add to 36 lb to make it 60% cashews
Answers
Answer:
13.5 lbs
Step-by-step explanation:
The number of pounds to be added with 36 lb to make cashews nut 60% is 12 pounds.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
45% cashew nuts = 36 lb
Multiply 60/45 on both sides.
60% = 60/45 x 36 lb
60% = 48 lb
The number of pounds to be added.
= 48 - 36
= 12 lb
Thus,
12 pounds of cashew should be added to 36 lb to make it 60% cashews.

A landscaper used 2 1/2 tons of sunburst pebbles, 3 1/4 tons of black polished pebbles, and ton of river pebbles. What was the total weight of the pebbles? 5/8
Answers
Answer:
6.375 tons or 6 3/8 tons
Step-by-step explanation:
According to Given data, calculation are as follows,
Sunburst pebbles = 2 1/2 tons or 2.5 tons
Black polished pebble = 3 1/4 tons or 3.25 tons
River pebble = 5/8 tons or o.625 ton
So, total weight of pebbles are as follows,
Total weight = 2.5 tons + 3.25 tons + 0.625 ton
= 6.375 tons or 6 3/8 tons
Hence, total weight of pebbles was 6 3/8 tons.
The measure of the angles of a triangle are in the extended ratio of 3 : 7 : 10. Find the measures of the angles.
A. 27 degrees, 63 degrees, 90 degrees
B. 30 degrees, 60 degrees, 90 degrees
C. 30 degrees, 70 degrees, 100 degrees
D.33 degrees, 77 degrees, 80 degrees
Answers
Answer:
A. 27 degrees, 63 degrees, 90 degrees.
Step-by-step explanation:
Let the angle of the triangle be x
Given the following data;
3 : 7 : 10 = 3x : 7x : 10x
We know that the sum of the sides of a triangle is equal to 180 degrees.
3x + 7x + 10x = 180
20x = 180
x = 180/20
x = 9
For the first side;
3x = 3 × 9 = 27°
For the second side;
7x = 7 × 9 = 63°
For the third side;
10x = 10 × 9 = 90°
Therefore, the ratio of the angles of the triangle is 27° : 63° : 90°.
Answer:
The measure of the angles of a triangle are in the extended ratio of 3 : 7 : 10. Find the measures of the angles.

At the beginning of 2010, City A had a population of 2,425 and was growing by 27 residents per year. City B had a population of 1,813 and was growing by 63 residents per year. If this trend continues in what year will the populations of the two cities be the same?
Answers
Answer: 17 years
Step-by-step explanation:
City A is currently 2,425 people in number and growing at 27 per year.
An expression to find the population in a given year assuming the year is x would be:
= 2,425 + 27 * x
= 2,425 + 27x
Applying the same logic to City B would give an expression of:
= 1,813 + 63x
Equating these together will give the year they will be the same:
2,425 + 27x = 1,813 + 63x
2,425 - 1,813 = 63x - 27x
612 = 36x
x = 612/36
x = 17 years

The answer for combine y and 7 are 7a, 7 +y, 7 - y and 7/y.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now the given statement is,
combine y and 7
Now a variable is a symbol (usually a letter) that stands for a value that may vary.
Here y is our variable.
When we combine numbers and variables in a valid way, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions, the resulting combination of mathematical symbols is called a mathematical expression.
Thus, combining y and 7 may have result as-
7a, 7 +y, 7 - y and 7/y.
Thus, the answer for combine y and 7 are 7a, 7 +y, 7 - y and 7/y.
