What is an explanation of a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.number of cats = n
number of fleas per cat = 2n
total number of fleas = (number of fleas per cat) * (number of cats) = 2n * n = 2n2
If we take the total number of fleas, subtract the fleas of two cats, then subtract 3 for every remaining cat, we get half the total number of fleas.
(total number of fleas) - 2(number of fleas per cat) - 3(n - 2) = (total number of fleas)/2
2n2 - 2(2n) - 3(n - 2) = (2n2)/2
2n2 - 4n - 3n + 6 = n2
Subtract n2 from both sides and combine like terms.
n2 - 7n + 6 = 0
Factor the left side
(n - 6)(n - 1) = 0
n = 6 or n = 1
n must be 6 because we can't remove 2 cats if there is only 1 cat to begin with.

What are examples of linear equations?
An equation with only one variable is referred to as a linear equation in one variable. It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.Step 1 - Write the equation.
3/a + 2 - 6a/a² - 4 = 1/a - 2
Step 2 - rewrite the equation.
3/a + 2 - 6a/a² - 4 = 1/a - 2
Step 3 - Take the LCM.
3(a- 2) - ( a + 2 )/a² - 2² = 6a/a²-4
Step 4 - Further simplify the above expression
3a - 6 - a - 2/a² - 4 = 6a/a² - 4
Step 5 - Cancel out the denominator of both sides and then further simplify.
2a - 8 = 6a
a = -2

Answer:
The perpendicular slope is the negative reciprocal of the original slope:
For example: the perpendicular slope for y/x is -x/y
In this case, we want the slope from x +4y = 28
x +4y = 28
4y = 28 - x
y = 7 -x/4

-j + 0.8 = -0.9j + 0.76
What is the answer :D
Answer:
j = 0.4
Step-by-step explanation:
hope it helps
To answer this question, you should combine like terms:
Like terms are two or more terms that share the same variable.
J is the variable in this question so add 0.9j to both sides of the equation to get j on one side:
-0.1j + 0.8 = 0.76
Now subtract 0.8 from both sides to isolate j on one side of the equation:
-0.1j = -0.04
Divide both sides by -0.1 to isolate j and your answer should be:
Answer: j = 0.4

If he earned $64 in 8 hours then dividing by 64 by 8 will tell us how much he earned in 1 hour. That gives $8
Using that we can then divide the number of dollars by the amount he receives in 1 hour to see how many hours it was.
So $16 / $8 per hour gives 2 hours
A new soup recipe contains 33\%33%33, percent less sodium per serving than the old soup recipe. The old soup recipe contained xxx milligrams of sodium per serving.
Which of the following expressions could represent the amount of sodium per serving, in milligrams, in the new soup recipe?
The expression that represents the amount of sodium per serving in the new soup is 0.67x milligrams.
How to find the expression that could represent the amount of sodium in the new soup?The new soup recipe contains 33%, percent less sodium per serving than the old soup recipe. The old soup recipe contained x milligrams of sodium per serving.
The expression that can be used to represent the amount of sodium per serving in milligrams in the new soup can be computed as follows;
Old soup amount of sodium = x milligram
The new soup contains 33% less sodium per serving than the old soup recipe.
Therefore,
amount of sodium per serving in the new soup = x - 33% of x
amount of sodium per serving in the new soup = x - 33 / 100 x
amount of sodium per serving in the new soup = x - 0.33x
Therefore,
amount of sodium per serving in the new soup = x(1 - 0.33)
amount of sodium per serving in the new soup = x(0.67)

A rectangular storage container without a lid is to have a volume of 10 m3. The length of its base is twice the width. Material for the base costs $20 per square meter. Material for the sides costs $12 per square meter. Find the cost (in dollars) of materials for the least expensive such container. (round your answer to the nearest cent. ).
The cost of materials for the least expensive such container is $327.081 .
In the question ,
it is given that
the volume of the container = 10 m³ .
let the width of the container = x
so , the length of the container = 2x
So , base area = 2x*x = 2x²
cost for base = $20
cost for the sides = $12
Since the volume is 10 m³
Volume = base area * height
10 = 2x² * h
h = 10/2x²
h = 5/x²
The cost of making the container
cost of base = 2x² * (20) = 40x²
cost of sides = [2*2x*(5/x²) + 2*x*(5/x²)](12)
= 360/x
the total cost of the container [tex]=[/tex] cost of base [tex]+[/tex] cost of sides
= 40x² + 360/x
= 40( x² + 9/x)
to get the minimum cost , we differentiate with respect to x and equate to 0
= 40 ( 2x - 9/x²)
2x - 9/x² = 0
2x³ = 9
x³ = 9/2
x³ = 4.5
x = 1.651
Substituting x in the cost equation ,
we get
Cost = 40x² + 360/x
= 40(1.651)² + 360/(1.651)
= 109.032 + 218.049
= 327.081
Therefore , The cost of materials for the least expensive such container is $327.081 .

Answer: 422.39
Step-by-step explanation:
To find the shaded region (I'm assuming it's the area inside the circle but outside the rectangle), subtract the area of the rectangle from the area of the circle.
The formula for circle area: πr^2
r is the radius, and it is given that r = 12, so the area of the circle is:
π * 12^2 ---> 144π is the area of the circle
Next, find the area of the rectangle: 3 * 10 = 30
Finally, find subtract the area of the rectangle from the area of the circle to find the shaded region:
144π - 30 ≈ 422.39
The length and width of a rectangle are consecutive integers. The perimeter of the rectangle is 54 centimeters. Find the length and width of the rectangle.
Thank you!
Answer:
length = 13 cm and width = 14 cm
Step-by-step explanation:
let n be the length then n + 1 is the width
the perimeter (P) of a rectangle is calculated as
P 2(l + w) ← l is length and w is width
given P = 54 , then
2(n + n + 1) = 54 ( divide both sides by 2 )
2n + 1 = 27 ( subtract 1 from both sides )
2n = 26 ( divide both sides by 2 )
n = 13
n + 1 = 13 + 1 = 14
length = 13 cm and width = 14 cm

Two cell phone plans offer differing text packages. The two plans are outlined below:
Plan A: $5.00 per month charge along with a charge of $0.03 per text.
Plan B: No per month charge,but a charge of 0.10 per text. Is there a certain number of texts,when the two plans cost the same amount? Determine your answer by setting up a system of equations that model the two plans.
The system of equation for the given condition is: 5+0.03x = 0.10x, where x is the number of texts.
There is no certain number of texts for which two plans are equal.
Let the number of texts for which two plans amount to same number be = x
Plan A: $5.00 per month charge along with a charge of $0.03 per text.
So, Plan A: 5+0.03x
Plan B: No per month charge but a charge of 0.10 per text.
Plan B: 0.10x
Since the plans amounted to same for x texts. So, the suitable system of equation is,
5+0.03x = 0.10x
Solving the equation we get,
0.10x - 0.03x = 5
0.07x = 5
x = 5/0.07 = 71.42 (approximately)

a) The bearing of Wellington from Gisborne is 232°
b) The bearing of Wellington from Auckland is 175.37°
How to solve bearing problems?We are given that AW = 410 km and GW = 400 km.
a) AG is a transversal intersecting two parallel lines N₁A and N₂B and ∠N₁AG = 115°.
Thus;
∠AGN₂ = 180 − 115 = 65°
since the sum of the interior angles on the same sides of the transversal intersecting two parallel lines are supplementary.
Thus;
∠N₂GW = 65 + 63 = 128°.
The reflex angle;
∠N₂GWW = 360 − 128° = 232°
b) In △AGW, we can say that by the sine rule;
(sin∠WAG)/WG = (sin∠AGW)/AG
Plugging in the relevant values;
(sin∠WAG)/400 = (sin∠63°)/410
Solving for ∠WAG gives; ∠WAG = 60.37°
Then;
∠N₁AW = 115 + 60.37
∠N₁AW = 175.37°
