A variable is a letter, for example x, y or z, that represents an unspecified number.
6+x=12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.Step-by-step explanation:
What is the equation of the line with a gradient of −2 which passes through the point (3, −5)?
Answer:

Step-by-step explanation:
Answer:
0
Step-by-step explanation:
To find the value of x, we first find the fraction that is equivalent to 1/3 that has a denominator of 12.
Multiplying or dividing the numerator and denominator of
a fraction by the same number will give us an equivalent fraction.
So if we multiply both the numerator and denominator of
the first fraction by 4, we can see that 1/3 = 4/12.
So the value of x must be 4.

The simplified expression is 7x- 2.
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
−4x−2y+6 from 3x−2y+4.
So, subtraction will be as follows
3x - 2y + 4-( -4x -2y + 6 )
or, 3x - 2y + 4 + 4x + 2y -6
or, 7x - 2
Hence, the simplified expression is 7x- 2.

If there are four black kittens and two orange kittens how does the number of orange kittens compared to the total number of kittens in the litter write a comparison beginning with for every?
Answer:
For every two black kittens, there is one orange kitten.
Step-by-step explanation:
Simplify the ratio and put it in word form.
Answer:
For every three kittens there is one orange kitten
Step-by-step explanation:
The total number of kittens is equal to four black kittens + two orange kittens, which makes for six kittens.
So for every six kittens there are two orange kittens.
We can simplify this down further by dividing by the greatest common factor, 2.
So,
For every three kittens there is one orange kitten.

Find the area of the metal sheet below that is required to make this square-shaped traffic sign. (note: square the binomial)
If 134n = 54eight , calculate n
The value of 'n' is approximately 4.0896.
To calculate the value of 'n' in the equation 134n = 548, we can isolate 'n' by dividing both sides of the equation by 134.
134n = 548
Dividing both sides by 134:
n = 548 / 134
Evaluating the division:
n ≈ 4.0896
Therefore, the value of 'n' is approximately 4.0896.
