Answer:
The answer is 8.
Step-by-step explanation:
Plugging in n and m in the equation, we have,
0.1 * (30) + 8 - (12) * (1/4) = ? → equation 1
Then we apply PEMDAS to solve.
Solve 0.1 * 30 first; 0.1*30 = 3
Then 12 * 1/4; 12 * 1/4 = 3
Put the values from above to equation 1
Now we have 3 + 8 - 3 = ?
Keeping the PEMDAS in mind, addition first before subtraction.
3 + 8 = 11
11 - 3 = 8
Therefore the answer is 8.
