Answer 1

pick an answer choice I provided.

Answer 2

To evaluate x over y + 3z^2 with x = three tenths (0.3), y = 4 over 5 (4/5), and z = 3, we substitute these values into the expression:

0.3 / (4/5 + 3(3)^2)

Simplifying, we have:

0.3 / (4/5 + 3(9))

0.3 / (4/5 + 27)

0.3 / (4/5 + 27/1)

0.3 / (4/5 + 135/5)

0.3 / (139/5)

Next, we divide 0.3 by 139/5:

0.3 * (5/139)

This simplifies to:

1/69 or approximately 0.0145

Therefore, the evaluated value of x over y + 3z^2 is 1/69 or approximately 0.0145.

Answer 3

The answer choice that matches the evaluated value is "two hundred nineteen over eight."
