Answer:
The length is 81 feet.
Step-by-step explanation:
If you plot the equations for both length and width on a graph, making them both equal to y of course, you find that they cross each other in two places. The places they cross are (81, 11) and (70, 0). It is impossible for the answer to have the width as 0 feet, so the answer is 81 feet.

Answer:
Jerry solved the system of equations.
x minus 3 y = 1. 7 x + 2 y = 7.
As the first step, he decided to solve for y in the second equation because it had the smallest number as a coefficient. Max told him that there was a more efficient way. What reason can Max give for his statement?
The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.
The variable x in the second equation has a coefficient of 7 so it will be easy to divide 7 by 7.
The variable y in the second equation has a coefficient of 2 so it will be easy to divide the entire equation by 2.
The variable x in the second equation has the largest coefficient. When dividing by 7, the solution will be a smaller number.

The 7th grade students at Palm Coast Middle School made some apple pies for a bake sale. The school cafeteria also donated 9 pies toward the effort. All the pies at the sale were cut into 8 pieces. If at least 224 pieces of pie were sold in all, how many pies did the students bake?
Answers
Answer:
19 i think
Step-by-step explanation:
Answer:
The students baked at least 19 pies.
Step-by-step explanation:
We know that each of the pies were cut into 8 pieces. Since the students sold at least 224 pieces of pie, we can use these equations to figure out how many pies were sold and how many were made by the students.
Total number of pies = total number of slices sold/number of slices per pie
Total number of pies = 224/8
Total number of pies = 28
Pies made by students= total number of pies-pies made by school cafeteria
Pies made by students= 28-9
Pies made by students= 19
The gasoline tank in Deborahs car holds 13.2 gallons. When her gas gauge says that the tank is 1/4 full, how many gallons of gasoline does the tank have?
Answers
Answer:
3.3
Step-by-step explanation:
To find the amount of gasoline when Deborah's tank is 1/4 full, divide the tank's full capacity (13.2 gallons) by 4, which results in 3.3 gallons of gasoline in the tank at 1/4 full.
To find out how many gallons of gasoline Deborah's car has when the tank is 1/4 full, we need to calculate 1/4 of the total capacity of the tank. Since the tank holds 13.2 gallons when full, the amount of gasoline at 1/4 full is calculated as follows:
Divide the full tank capacity by 4 to find 1/4 of the tank's capacity: 13.2 gallons / 4 = 3.3 gallons.Therefore, when Deborah's gas gauge indicates that the tank is 1/4 full, it contains 3.3 gallons of gasoline.
What is the slope of a line that is parallel to the line shown in this graph?
Answers
Answer:
The slope of the parallel line is 2/3
Step-by-step explanation:

Which of the following is true about the expression given below?
9>2
A.9 is to the left of 2 on a horizontal number line.
B.9 is the opposite of 2 on a horizontal number line.
C.9 is to the right of 2 on a horizontal number line.
D.9 is at the same place as 2 on a horizontal number line.
Answers
Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
9 > 2
i.e. 9 is to the right of 2 on a horizontal number line
As we know that in the Cartesian plane, upper most is for y- positive coordinate, lower most is for y- negative coordinate
Similarly, right most is for x-positive coordinate and left most is for x- negative coordinate.
And we have 9>2
Both 2 and 9 are positive numbers so, both numbers must be in the right part of axis.
And 9 is always right of 2 on a horizontal number line.
Hence, Option 'C' is correct.
x − 2y = 14
x + 3y = 9

The multiplication of two or more quantities may be expressed as the ? of the same quantities.
Answers
Answer:
sum
Step-by-step explanation:
We have that, 'The multiplication of two or more quantities may be expressed as the repeated addition of the same quantities'.
i.e. multiplication of two or more terms is equal to adding as many copies of one of them.
i.e. a × b = a + a + ... ( 'b' number of times ) = b + b + .... ( 'a' number of times )
For example,
2 × 4 = 8
2 × 4 = 2 + 2 + 2 + 2 = 8 i.e. adding 2 four times
2 × 4 = 4 + 4 = 8 i.e. adding 4 two times
or
3 × 7 = 21
3 × 7 = 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21 i.e. adding 3 seven times
3 × 7 = 7 + 7 + 7 = 21 i.e. adding 7 three times.
Hence, 'The multiplication of two or more quantities may be expressed as the repeated addition of the same quantities'.
The multiplication of two or more quantities can be expressed as the product of the same quantities in mathematics.
Explanation:Multiplication is a fundamental arithmetic operation that combines two or more numbers to find their total value. It represents repeated addition and is denoted by the "×" or "*" symbol. For example, multiplying 5 by 3 results in 5 * 3 = 15, indicating that the value is added five times.
In mathematics, the multiplication of two or more quantities may be expressed as the product of the same quantities. For example, if you multiply 2 by 3, the product is 6. This concept of multiplication applies to all quantities, whether they are numbers or variables.

Describe a sequence of transformations that transforms the graph of the parent function f into the graph of the function g.
f(x)= x
g(x)= -3(x-4)+1
Answers
Step-by-step explanation:
Parent function f(x) = x
g(x)= -3(x-4) + 1
If any number added or subtracted with x then graph moves left or right
Here 4 is subtracted from x, so graph move 4 units to the right
If any number added or subtracted at the end then graph move up or down
Here 1 is added at the end, so graph move 1 unit up.
g(x) = -f(x), for negative sign the graph reflects across x axis
We have negative sign at first, so the graph reflects over x axis
The graph of [tex]\( g(x) \)[/tex] is the result of these transformations applied to the graph of the parent function [tex]\( f(x) \)[/tex].
The sequence of transformations that transforms the graph of the parent function [tex]\( f(x) = x \)[/tex] into the graph of the function [tex]\( g(x) = -3(x-4)+1 \)[/tex] involves a reflection across the x-axis, a horizontal shift, a vertical stretch, and a vertical shift.
1. Reflection across the x-axis: The negative sign in front of the function[tex]\( g(x) \)[/tex]indicates a reflection across the x-axis. This means that for every point \( (x, y) \) on the graph of [tex]\( f(x) \)[/tex], there will be a corresponding point [tex]\( (x, -y) \)[/tex] on the graph of [tex]\( g(x) \)[/tex].
2. Horizontal shift: The expression [tex]\( (x-4) \)[/tex] inside the function [tex]\( g(x) \)[/tex]indicates a horizontal shift to the right by 4 units. This means that every point on the graph of [tex]\( f(x) \)[/tex] is moved 4 units to the right along the x-axis to get the graph of [tex]\( g(x) \).[/tex]
3. Vertical stretch: The coefficient 3 in [tex]\( -3(x-4) \)[/tex] indicates a vertical stretch by a factor of 3. This means that for every point [tex]\( (x, y) \)[/tex] on the graph of the reflected function[tex]\( -f(x) \)[/tex], the y-coordinate is multiplied by 3 to get the corresponding point [tex]\( (x, 3y) \)[/tex] on the graph of [tex]\( g(x) \)[/tex].
4. Vertical shift: Finally, the[tex]\( +1 \)[/tex] at the end of the function [tex]\( g(x) \)[/tex]indicates a vertical shift upwards by 1 unit. This means that every point on the graph of [tex]\( -3f(x-4) \)[/tex] is moved 1 unit up along the y-axis to get the graph of [tex]\( g(x) \).[/tex]
Putting it all together, the sequence of transformations is as follows:
- Start with the parent function [tex]\( f(x) = x \).[/tex]
- Reflect the graph across the x-axis to get [tex]\( -f(x) \).[/tex]
- Shift the graph 4 units to the right to get [tex]\( -f(x-4) \).[/tex]
- Stretch the graph vertically by a factor of 3 to get [tex]\( -3f(x-4) \).[/tex]
- Shift the graph 1 unit upwards to get [tex]\( -3f(x-4) + 1 \),[/tex] which is the function [tex]\( g(x) \)[/tex].
Therefore, the graph of [tex]\( g(x) \)[/tex] is the result of these transformations applied to the graph of the parent function [tex]\( f(x) \)[/tex].

Simplify 0.3x + 0.6 + 2.11 to 0.3x + 2.71
4x - 28 = 0.3x + 2.71
Add 28 to both sides
4x = 0.3x + 2.71 + 28
Simplify 0.3x + 2.71 + 28 to 0.3x + 30.71
4x = 0.3x + 30.71
Subtract 0.3x from both sides
4x - 0.3x = 30.71
Simplify 4x - 0.3x to 3.7x
3.7x = 30.71
Divide both sides by 3.7
x = 30.71/3.7
Simplify 30.71/3.7 to 8.3
x = 8.3

Find the value of x and y
Answers
Answer:
x=90: y =43
Step-by-step explanation:
Given is a triangle. In ABC, AB = AC is given. also angle C = 47 is given.
AD is angle bisector of angle A
Since two sides are equal, ABC is isosceles. We have angle C = angle B
Hence angle B = 47 degrees.
Angle A = 180-(B+C) = 180-94 = 86
So angle y = 1/2 (86) = 43
Consider triangle BAD.
We have got two angles as 47 and 43.
Hence third angle is 180-(47+43) = 90
So x=90, y = 43

So, It does not matches the equation
B: The year before, when the students were in seventh grade, there were 25 students.
Let g be the no. of students added between seventh and eighth grade
So, Total students = 25+g
We are given that The eighth-grade class has 34 students.
So, equation becomes : 34=g+25
It matches the equation.
C :A person bikes 34 miles on Monday
He bikes 25 miles on Tuesday.
So, Total miles =25+34
So, It does not matches the equation
D: Jack has 25 marbles.
Mary gives him 34 marbles.
Total marbles = 25+34
So, It does not matches the equation
Hence Option B matches the equation
Fred brown and his sister, Nancy, each have $15 in the bank. Every week Nancy plans to add $3 to her account. Fred who loves to spend money when he has it, plans to add $1 to his account each week. How many weeks will it take Nancy’s account to have TWICE as much money as Fred’s account?
(Explain your thinking)
Answers
Answer:
it will take 15 weeks for Nancy’s account to have TWICE as much money as Fred’s account
Step-by-step explanation:
Fred brown and his sister, Nancy, each have $15 in the bank
Initially both Fred and Nancy have $15
Every week Nancy plans to add $3 to her account
Let 'n' be the number of weeks she plans to add in her account
for 1 week, $3
For n weeks , its 3n
So amount of money in Nancy's account after 'n' weeks = 15 + 3n
Fret plans to add $1 to his account each week
for 1 week, $1
For n weeks , its 1n
So amount of money in Fred's account after 'n' weeks = 15 + 1n
Now we need to find out 'n' when
Nancy's account = 2 times of Fred's account
15 + 3n = 2(15+1n)
Distribute 2 inside the parenthesis
15 + 3n = 30 + 2n
Subtract 2n on both sides
15 + n = 30
Subtract 15 on both sides
n = 15
Hence, it will take 15 weeks for Nancy’s account to have TWICE as much money as Fred’s account
