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.
Answer:
24 m²
Step-by-step explanation:
The area of a rhombus is the product of the two diagonals over 2
Answer:
Step-by-step explanation:
The equation for this is 3x + 5x + 4x = 600 where x is the same amount of money multiplied by the scalar value to ensure the money is divided in that ratio exactly. That gives us 12x = 600.
x = 50.
The largest value is 5(50) = 250 and
the smallest value is 3(50) = 150.
The difference between these is $100.
Answer:
The answer is 1/9 ⇒ the second answer
Step-by-step explanation:
* In the exponential functions we have some rules
(1) b^(-m) = 1/(b^m) (for all nonzero real numbers b)
- If we have negative power we reciprocal the base
to get positive power
(2) (b^m)^n = b^(mn)
- If we have power over power we multiply them
* In our problem: 
- At first change 27 to b^n
∵ 27 = 3 × 3 × 3 = 3³
∴ 
* Lets use rule (2)
∴ 
⇒ 3 × -2/3 = -2
* Use rule (1)
∴ 
⇒ reciprocal the fraction to change the sig of the power
* The answer is 1/9
