Answer:
The correct answer is x = 6.
Step-by-step explanation:
To solve this problem, we first must recognize that DE + EF = DF.
From this information, we can set up the following equation when we substitute in the given values:
DE + EF = DF
(4x-1) + 9 = 9x - 22
Our first step is going to be to combine like terms on the left side of the equation. This is modeled below:
4x - 1 + 9 = 9x - 22
4x + 8 = 9x - 22
Then, we should subtract 4x from both sides of the equation.
8 = 5x - 22
Now, we can add 22 to both sides of the equation.
30 = 5x
Finally, we can divide both sides by 5.
x = 6
Therefore, the correct answer is x = 6.
Hope this helps!

Mason loves collecting sea glass from the beach. He recorded the weight of each jar full of sea glass. If he decided to distribute the sea glass equally among the jars, how much would each jar weigh? pounds (Write mixed numbers as x y/z.)
The missing weights are:
2 2 2 1 11 12 12 2 24 22 24 3 37 22
Answer:
[tex]Average = 12\frac{4}{7} \ lb[/tex]
Step-by-step explanation:
Given
Weight of sea glass
To solve this question, we have to calculate the mean of the weight of the sea glass as follows;
[tex]Average = \frac{\sum x}{n}[/tex]
Where n = number of sea glass
[tex]n = 14[/tex]
So:
[tex]Average = \frac{\sum x}{n}[/tex] becomes
[tex]Average = \frac{2 +2 + 2 + 1 + 11 +12 +12 +2 +24+22 +24 +3 +37+ 22}{14}[/tex]
[tex]Average = \frac{176}{14}[/tex]
[tex]Average = 12\frac{8}{14}[/tex]
Simplify fraction
[tex]Average = 12\frac{4}{7}[/tex]
Hence; the weight of the sea glass would be [tex]12\frac{4}{7}\ lb[/tex] when evenly distributed...

You install 404 feet of fencing along the perimeter of a rectangular yard.
The width of the yard is 100 feet. What is the length of the yard?
Answer:
The length of the yard is 102
Step-by-step explanation:
If the width of the yard is 100 feet, and it's a rectangular, that means the other side of the rectangle is also equal to 100 feet. So so far we have 200 feet of the yard covered. Then we do 404-200=204. So the combined length of both the sides is 204. Since they both equal the same length, we can then do 204/2 to get 102. So one side length is 102 and the L, W, L, W of the rectangle is 102, 100, 102, 100. In other words, the rectangle is 102 by 100.
Answer:
Length of the yard = 102 ft
Step-by-step explanation:
Perimeter of the yard P = 404 ft
Width of the yard W = 100 ft
Find Length of the yard L = ?
Perimeter of a rectangular = 2L + 2W
404 = 2L + 2(100)
2L = 404 - 200
2L = 204
L = 204 / 2
L = 102 ft

Answer:
p = 8
Step-by-step explanation:
Let one root of the eqn. be alpha . Other root is 1/alpha .
We know that product of both roots of an quadratic eqn. is c/a where "c" is the co-efficient of the constant & "a" is the co-efficient of x^2.
Here "c" is p-4 & "a" is 4. And the product of roots is 1 ( ∵ prdouct of a number and its reciprocal is 1 )

Maggie baked a berry pie. The recipe called for 6 ounces of blackberries, 9 ounces of raspberries, and 5 ounces of strawberries. In the supermarket, she only found 12-ounce containers of berries. She bought 1 container of each kind of berry. After she baked the pie, how many ounces of berries did Maggie have left?
Answer:
16 berries
Step-by-step explanation:
Blackberries: 12 - 6 = 6Raspberries: 12 - 9 = 3Strawberries: 12 - 5 = 7 Now we know how many individual berries will be left: 6 blackberries, 3 raspberries, and 7 strawberries.6 + 3 + 7 = 16As of 2016 New York City has a population of 8.55 million and a land area of 300 square miles. Manhattan is a section of New York City that has a land area of 23 square miles and a population of 1.64 million.
How much greater is the population density of Manhattan than that of New York City?
Answer:
42,804.35 million people per miles
Step-by-step explanation:
Population density = Number of people / Land area
New York
Population = 8.55 million
Land area = 300 square miles
Manhattan
Population = 1.64 million
Land Area = 23 Square miles
Population density of New York = Number of people / Land area
= 8.55 million / 300 Square miles
= 8,550,000 / 300
= 28,500 people per square miles
Population density of Manhattan = Number of people / Land area
= 1.64 million / 23 miles
= 1,640,000 / 23
= 71,304.35 million people per square miles
Difference between Manhattan and new York City = 71,304.35 - 28,500
= 42,804.35 million people per miles
Therefore,
The population density of Manhattan is greater than that of New York City by 42,804.35 million people per miles
The difference between the population densities of Manhattan and New York is 42,804 people per square mile.
The density of New York is:
= Population / Area
= 8,550,000 / 300
= 28,500 people per square mile
Density of Manhattan:
= 1,640,000 / 23
= 71,304 people per square mile
The difference is:
= 71,304 - 28,500
= 42,804 people per square mile
In conclusion, Manhattan's population density is 42,804 people per square mile higher than New York City's.

What common error(s) did this student make? What is the correct solution for x? Please help
Answer:
10x - 5(x - 1) = 20
10x - 5x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
The first error was in the 2nd line: -5(x - 1) is -5x + 5, not -5x - 5 = 20.
Continuing the solution:
10x - 5x + 5 = 20
Combining like terms, we get
5x = 15, and so x = 3
Triangle ABC is shown below. Triangle A B C is shown. The length of side A B is 2 x, the length of side B C is 4 x minus 10, and the length of side A C is 3 x minus 7. Angle A B C and B C A are congruent. What is the length of line segment AC? 7 9 14 18
The length of line segment AC of the given triangle is; 14
How to find the length of the line segment?Since Angle ABC and BCA are congruent, it means that they are equal.
An isosceles triangle is a triangle that has two equal sides and two equal base angles.
Now, since Angle ABC and BCA are equal, it means that the triangle is an isosceles triangle. It also means that sides AC and AB are equal. The expression becomes;
3x - 7 = 2x
3x - 2x = 7
x = 7
To determine the length of line segment AC. We will substitute x = 7 into 3x - 7. It becomes

Liam's breakfast was an egg and cheese biscuit with a carton of milk. He spent a total of $5.65. Finn spent $7.65 on an egg and cheese biscuit and two cartons of milk. How much was an egg and cheese biscuit?
Answer:
An egg and cheese biscuit was $3.65.
Step-by-step explanation:
Liam's breakfast was:
[tex] P = E + C + M [/tex]
Where:
P: total price
E: egg
C: cheese biscuit
M: carton of milk
[tex] P = E + C + M [/tex]
[tex] 5.65 = E + C + M [/tex] (1)
Now, Finn's breakfast was:
[tex] P = E + C + 2*M [/tex]
[tex] 7.65 = E + C + 2*M [/tex] (2)
By subtracting equation (2) from (1) we have:
[tex] 7.65 - 5.65 = 2M - M [/tex]
[tex] M = 2 [/tex]
Hence, the price of a carton of milk is $2, so by entering this value into equation (1) we can find the price of an egg and cheese biscuit:
[tex] 5.65 = E + C + M [/tex]
[tex] 5.65 - 2 = E + C [/tex]
[tex] E + C = 3.65 [/tex]
Therefore, an egg and cheese biscuit was $3.65.
