The algebraic expression for two-fifths of the square of a number will be (2/5)x².
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The square of the number means the number is multiplied by itself.
The algebraic expression for two-fifths of the square of a number will be
Let the number be x.
Then the square of the number will be
⇒ x²
And the two-fifth number is expressed as,
⇒ 2/5
The algebraic expression for two-fifths of the square of a number will be
⇒ (2/5)x²
Thus, the algebraic expression for two-fifths of the square of a number will be (2/5)x².

Answer:
r = 1
Step-by-step explanation:
We can combine like terms, getting -3r = -3.
Then we can divide both sides by -3, and get r = 1.
Answer:
r = 1
Step-by-step explanation:
First, we'll simplify
-5r + 2r = -3
-3r = -3
Then, we divide
-3 divided by - 3 is equal to 1
Therefore, r = 1

Answer:
y = -3x + 5
Step-by-step explanation:
Slope intercept form is y = mx + b.
To solve this, you have to rearrange the equation to leave y alone.
First, you have to subtract 6x from both sides, so 2y is alone.
6x - 6x + 2y = 10 - 6x
2y = -6x + 10
Then, you have to divide both sides by 2, so y is alone.
2y/2 = (-6x/2) + (10/2)
y = -3x + 5
