<<

=is equal to

≥is greater than or equal to

>is greater than

1 answer

To evaluate the expressions on both sides of the blank, we will solve the left side and the right side separately.

First, let's calculate the left side: \[ 6 - 14 \cdot 28 - 214 \] Following the order of operations:

  1. Calculate \(14 \cdot 28\): \[ 14 \cdot 28 = 392 \]
  2. Substitute this back into the expression: \[ 6 - 392 - 214 \]
  3. Now perform the subtraction: \[ 6 - 392 = -386 \]
  4. Then subtract 214: \[ -386 - 214 = -600 \]

Now, let's evaluate the right side: \[ 34 + 4 \cdot 2 - 11 \] Following the order of operations:

  1. Calculate \(4 \cdot 2\): \[ 4 \cdot 2 = 8 \]
  2. Substitute this back into the expression: \[ 34 + 8 - 11 \]
  3. Now perform the addition and subtraction: \[ 34 + 8 = 42 \] \[ 42 - 11 = 31 \]

Now we compare the results:

  • Left side: \(-600\)
  • Right side: \(31\)

The inequality we need to evaluate is: \[ -600 _ 31 \]

The correct operation that satisfies this inequality is: \[ -600 < 31 \]

Therefore, among the options provided, the correct operation to place in the blank is: \[ < \]

However, since this option is not listed, the most accurate selection regarding the choices given would be: \[ \text{is less than} \] (even though you can classify it as "is not greater than" which is more fitting with the given choices of ≥ or >).

But if restricted to the given options, none fit perfectly, as < is not an option to choose from. Therefore, the evaluation leads to:

No valid choice from the given options directly fits the blank—if forced to choose, we select based on the least contradiction, which is: \[ < \text{ (not available in options)} \] but recognize that technically one should say none of these apply.

Thus, from listed choices, none address that effectively.
