Answers & Comments
Answer:
1. Mathematical expression: (a + b + c) / (a * b * c)
Translation: The sum of three numbers divided by their product.
2. Mathematical expression: (2/3)y + x^2 = 13
Translation: Two-thirds of a number y added to the square of x is thirteen.
3. Mathematical expression: 2 * pi * r = C
Translation: The circumference of a circle is equal to twice the product of its radius and pi.
4. Mathematical expression: (a + b) * (a - b) = c
Translation: The product of the sum and difference of two numbers is equal to the difference of another number c.
5. Mathematical expression: (1/2)(x + y) + z^2
Translation: Half the sum of a number x and y added to the square of z.
