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.
To solve the given expression step-by-step, we'll follow the order of operations (also known as PEMDAS). PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
The given expression is:
*2small3 - 8 ÷ 4.2 + 7
First, there are no parentheses or exponents, so we move on to the next step.
Next, we perform the division from left to right:
8 ÷ 4.2 = 1.9047619047619047
Now, the expression becomes:
*2small3 - 1.9047619047619047 + 7
Next, we perform the multiplication:
2small3 * 1.9047619047619047 = 3.8095238095238093
Now, the expression becomes:
3.8095238095238093 - 1.9047619047619047 + 7
Next, we perform the subtraction and addition (from left to right):
3.8095238095238093 - 1.9047619047619047 + 7 = 9.904761904761905
Therefore, the solution to the given expression is approximately 9.9048.
To solve this problem, we need to follow the order of operations (also known as PEMDAS or BODMAS) to simplify the expression step by step.
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 division: 8 ÷ 4.2 = 1.9047619 (repeated to the required decimal places).
Thus, the expression becomes: 2small3 - 1.9047619 + 7
Step 3: Perform any addition or subtraction from left to right
Now, let's subtract 1.9047619 from 2small3: 2small3 - 1.9047619 = 21.0952381.
Finally, add 21.0952381 to 7: 21.0952381 + 7 = 28.0952381
Therefore, the solution to the given expression is approximately 28.0952381.

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.
