Answer 1

To solve the expression, we follow the order of operations (PEMDAS).

First, we perform the division:

8 ÷ 4.2 = 1.90476190476 (approximately)

Next, we multiply the result by 2:

1.90476190476 * 2 = 3.80952380952 (approximately)

Then, we subtract 3:

3.80952380952 - 3 = 0.80952380952 (approximately)

Finally, we add 7:

0.80952380952 + 7 = 7.80952380952 (approximately)

Therefore, the solution to the given expression is approximately 7.80952380952.

Answer 3

Apologies for the confusion. Upon revising the steps, it appears there was a mistake in multiplication.

Here is the corrected solution:

Step 1: Simplify within parentheses (if any)
There is no parentheses in the expression.

Step 2: Perform any multiplication or division from left to right
2small3-8 ÷4.2+7

First, let's perform the multiplication: 2small3 * 8 = 16.

Next, divide 8 by 4.2: 8 ÷ 4.2 = 1.9047619 (repeated to the required decimal places).

Thus, the expression becomes: 16 - 1.9047619 + 7

Step 3: Perform any addition or subtraction from left to right
Now, subtract 1.9047619 from 16: 16 - 1.9047619 = 14.0952381.

Finally, add 14.0952381 to 7: 14.0952381 + 7 = 21.0952381.

Therefore, the solution to the given expression is approximately 21.0952381.

Among the provided options, 14 is the closest value to the solution obtained.
