Answer:
In order to be called a 'rational' number, a number must be the quotient that results when one non-zero integer is divided by another. An irrational number can be written as a decimal, but not as a fraction. Your number is (3 sqrt(2)) / sqrt(2) = 3, and is a rational number indeed.

Anu borrowed Rs 4000 from a bank at 7 % per annum for 2 years. She then lent this amount to Nidhi at 9 % per annum for the same period. How much did Anu gain in this transaction?
Step-by-step explanation:
p- 4000
r- 7
t-2years
SI- P×r×t/100
SI-4000×7×2/100
SI- 4000×14/100
SI- 56000/100
SI- 560
so anu give = p+ SI
= 4000+560
= 4560 ₹
p- 4000
r- 9
t-2 years
SI- P×r×t/100
SI- 4000×9×2/100
SI- 4000×18/100
SI- 72000/100
SI- 720
so nidhi give= p+SI
= 4000+720
= 4720

(8x + 9) + (–6x – 1)
Answer:
5
Step-by-step explanation:
Simplifying
(8x + 9) + -1(6x + -1) = 0
Reorder the terms:
(9 + 8x) + -1(6x + -1) = 0
Remove parenthesis around (9 + 8x)
9 + 8x + -1(6x + -1) = 0
Reorder the terms:
9 + 8x + -1(-1 + 6x) = 0
9 + 8x + (-1 * -1 + 6x * -1) = 0
9 + 8x + (1 + -6x) = 0
Reorder the terms:
9 + 1 + 8x + -6x = 0
Combine like terms: 9 + 1 = 10
10 + 8x + -6x = 0
Combine like terms: 8x + -6x = 2x
10 + 2x = 0
Solving
10 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + -10 + 2x = 0 + -10
Combine like terms: 10 + -10 = 0
0 + 2x = 0 + -10
2x = 0 + -10
Combine like terms: 0 + -10 = -10
2x = -10
Divide each side by '2'.
x = -5
Simplifying
x = -5

. How many dozen must be sold to make a profit of $90? Make a Selection: A. 45 B. 25 C. 30 D. 8
Solve the system of linear equations below: y= 4x-9 y= x-3
[tex] \begin{cases} y = 4x - 9 \\ y = x - 3 \end{cases}[/tex]
We can combine both equations
[tex]4x - 9 = x - 3[/tex]
Solve the equation.
[tex]4x - x = 9 - 3 \\ 3x = 6 \\ x = \frac{6}{3} \longrightarrow \frac{2}{1} \\ x = 2[/tex]
Then we substitute the value of x in any given equations which I will be substituting in the second equation
[tex]y = x - 3 \\ y = 2 - 3 \\ y = - 1[/tex]
Therefore, from x = 2 and y = -1, the solution is (2,-1)
Answer Check
Substitute the value of x and y in both equations.
First Equatio
[tex]y = 4x - 9 \\ - 1 = 4(2) - 9 \\ - 1 = 8 - 9 \\ - 1 = - 1[/tex]
Second Equation
[tex]y = x - 3 \\ - 1 = 2 - 3 \\ - 1 = - 1[/tex]
Both equations are true for (2,-1).
Answer[tex] \begin{cases} x = 2 \\ y = - 1 \end{cases} \\ \sf \underline{coordinate} \\ (2,-1)[/tex]
Answer:
(2, - 1 )
Step-by-step explanation:
Given the 2 equations
y = 4x - 9 → (1)
y = x - 3 → (2)
Substitute y = 4x - 9 into (2)
4x - 9 = x - 3 ( subtract x from both sides )
3x - 9 = - 3 ( add 9 to both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting into (2)
y = 2 - 3 = - 1
solution is (2, - 1 )

The least number of socks to be taken from the pile to have one pair of socks is given by the equation A = 4
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of socks to be taken be represented as A
Now , the equation will be
The number of white socks = 12
The number of black socks = 12
The number of red socks = 12
So , let the first sock be taken be either a white , black or red
Now , the second sock can also be either a white , black or red
And , the third sock can also be either a white , black or red
But , the fourth sock must a white or black or red and it will form a pair of similar colored sock
Therefore , the number of times is 4
Hence , the number is 4
