Answer: $6.92
Step-by-step explanation: Whenever you see the word per in a math problem, that means division. So right now, you could set up an equation that looks like this. 20L=130.40 (let L mean cost per foot of lumber). If you want to find the cost per foot you need have 1L or just L on one side of the equation. Well, the easiest way to do that would be to divide by 20 on both sides. And that would get you L= 6.92. And since L means the cost per foot of lumber, that cost would be $6.92. Hope this helps!

What is the slope of the line through (0, 5) and (-2, -1)
Answer:
3
Step-by-step explanation:
To find the slope of a line going through two points, (x₁, y₁) and (x₂, y₂), we can use the following formula: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. Note that it doesn't really matter which points we call (x₁, y₁) or (x₂, y₂).
Let's call (x₂, y₂) = (0, 5) and (x₁, y₁) = (-2, -1). Now, we can plug in the values for x, y₁, x₂, and y₂ into the formula.
We have:
[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{5-(-1)}{0-(-2)} =\frac{5+1}{0+2} =\frac{6}{2} =3[/tex]
Therefore, the slope of the line is 3. Hope this helps!

Answer:
Option (3)
Step-by-step explanation:
Given inequality is,
-2x + 8 < 12
By subtraction property of Order,
-2x + 8 - 8 < 12 - 8
-2x < 4
B division property of Order,
[tex]\frac{-2x}{(-2)}<\frac{4}{(-2)}[/tex]
x > -2
Since, there is no sign of equal to ( = ) in the given inequality, starting point on a number line will be a hollow point.
And an arrow starting from point x = -2 directing towards positive integers will represent the given inequality.
Option (3) will be the answer.

Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Equality Properties
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
[Standard Form] -5x - 4y = -12
Step 2: Rewrite
Add 5x to both sides: -4y = 5x - 12Divide -4 on both sides: y = -5/4x + 3Step 3: Identify

3/2+(-6/5)?? answer??
Answer:
I think The answer would be 0.3
Answer:
-3/10
Step-by-step explanation:
3/2 is equivalent to 15/10. Or 1 5/10. And 6/5 is equivalent to 18/10s or 1 8/10. Therefore 1 1/5 + (-1 8/10) = -3/10

After paying seven dollars for the pie, Sara has ninety-six dollars left. How much money (m) did she have
before buying the pie? Do not include spaces in your answers.
Answer:
103
Step-by-step explanation:
bassically what you do is add 7 dollars to the ninety six that she lost when she bought the pie or you can do this equation 96 + m but m would be the money she lost being 7 dollars so you would replace m with 7 so it would be 96 + 7 = 103

Use Simplex Method and Maximize 2x+3y =z
Hello!
Solve for x.
2x+3y=z
Step 1: Add -3y to both sides.
2x+3y+−3y=z+−3y
2x=−3y+z
Step 2: Divide both sides by 2.
2x/2=−3y+z/2
Answer:x= −3/2y+1/2zThank you for asking this question!
It would be greatly appreciated if you thanked me and marked me as the brainliest!

is x^2 + 1/x = 4 a quadratic equations
Answer:
[tex]\large\boxed{\pink{ \leadsto The \ given \ equation \ is \ not \ a \ Quadratic \ equation . }}[/tex]
Step-by-step explanation:
Given equation to us is ,
[tex]\green{\implies x^2+\dfrac{1}{x}=4 }[/tex]
So , a equation is said to be a quadratic equation if the highest degree of the variable is 2 . On simplifying the Equation ,
[tex]\implies x^2 +\dfrac{1}{x}=4 [/tex]
Taking x as LCM ,
[tex]\implies \dfrac{x^2.x + 1 }{x}= 4 [/tex]
Transposing x to RHS .
[tex]\implies x^3 + 1 = 4x [/tex]
Putting all terms in LHS
[tex]\boxed{\bf \implies x^3 - 4x - 1 = 0 }[/tex]
Since here the highest degree of the variable is 3 not 2 . So its a cubic equation and not a quadratic equation .
Hence the given equation is not a quadratic equation .The length of a rectangle is 3 feet more than twice the width. Find its area if its perimeter is 7 1/3?
Plssss help me fast!!!!!!!!
Answer:
3+2w=l
2(l+w)=7 1/3
2(3+2w+w)= 7 1/3
6+6w= 7 1/3
-6 both sides
6w=1 1/3
/6 both sides
w=2/9
2/9*2=4/9+3=3 4/9
4/9*3 4/9= 1 43/81
1 43/81
Mr. Percuoco is working the fish bowl toss. He used 13.6 gallons of water to fill 40 fish bowls. If he put an equal amount of water in each one, how many gallons of water are in each fish bowl?
Answer:
0.34 gallons of water
Step-by-step explanation:
Mr Percuoco is working the fish bowl toss
He used 13.6 gallons of water to fill 40 fish bowls
Therefore the gallons of water in each fish bowl can be calculated as follows
= 13.6/40
= 0.34
Hence there are 0.34 gallons of water in each fish bowl

Elena walked 12 miles. Then she walked 0.25 that distance. How far did she walk altogether? Select all that apply.
Which values of a, b, and c correctly represent the answer in simplest forrn?
Answer:
The equation becomes
[tex]1\frac{7}{19}=a\frac{b}{c}[/tex]
Therefore,
a = 1b = 7c = 19Hence, option (C) is true.
Step-by-step explanation:
Given the expression
[tex]3\frac{1}{4}\div 2\frac{3}{8}\:=a\frac{b}{c}[/tex]
Solving the L.H.S of the equation
[tex]3\frac{1}{4}\div \:2\frac{3}{8}=\frac{13}{4}\div \:2\frac{3}{8}[/tex]
[tex]=\frac{13}{4}\times \frac{8}{19}[/tex]
[tex]=\frac{13\times \:2}{1\times \:19}[/tex]
[tex]=\frac{26}{1\times \:19}[/tex]
[tex]=\frac{26}{19}[/tex]
Converting improper fraction to a fixed number: [tex]\frac{26}{19}=1\frac{7}{19}[/tex]
[tex]=1\frac{7}{19}[/tex]
Thus, the equation becomes
[tex]1\frac{7}{19}=a\frac{b}{c}[/tex]
Therefore,
a = 1b = 7c = 19Hence, option (C) is true.
