Answer:
I think that it should be
Step-by-step explanation:
Here,
we take , a - b = A,b-c = B , c - a= C
A+B+C = 0
we know that,
Here , A+B+C = 0
so,
A^3 +B^3 + C^3 = 3 ABC
now we put the values
I am done .
Wide ruled paper has typically a total of 27 lines. The space of a wide ruled notebook paper is 8mm. The ruled paper and line paper is similar to each other but college ruled paper is different from wide ruled paper because wide ruled paper has fewer and bigger lines than college ruled paper.
Hello! The tax rate is 8%. To find the total price paid for the television, let's first add 1 to the percentage in decimal form. 8% is 0.08. 1 + 0.08 is 1.08. Multiply that number by 330 to get 356.4. There. May pays a total of $356.40 for the television.
Note: When it comes to skipping straight to the total amount with tax, always add 1 to the tax rate (tax rate should be in decimal form). This will take you straight to the answer and save you some time and paper.
Answer:
{x,y,z}={5,−3,3}
Step-by-step explanation:
[1] 2x + 4y + z = 1
[2] x - 2y - 3z = 2
[3] x + y - z = -1
// Solve equation [3] for the variable y
[3] y = -x + z - 1
// Plug this in for variable y in equation [1]
[1] 2x + 4•(-x +z -1) + z = 1
[1] -2x + 5z = 5
// Plug this in for variable y in equation [2]
[2] x - 2•(-x +z -1) - 3z = 2
[2] 3x - 5z = 0
// Solve equation [2] for the variable x
[2] 3x = 5z
[2] x = 5z/3
// Plug this in for variable x in equation [1]
[1] -2•(5z/3) + 5z = 5
[1] 5z/3 = 5
[1] 5z = 15
// Solve equation [1] for the variable z
[1] 5z = 15
[1] z = 3
// By now we know this much :
x = 5z/3
y = -x+z-1
z = 3
// Use the z value to solve for x
x = (5/3)(3) = 5
// Use the x and z values to solve for y
y = -(5)+(3)-1 = -3
Solution :
{x,y,z} = {5,-3,3}
Multiply .15 by 24 to get your answer. The answer would be 3.6 which is $3.60 as your tip
