Verified answer

Answer:

35

Step-by-step explanation:

1. 16-4+8 = 20

Explanation: Follow the order of operations - subtraction should be done before addition.

16 - 4 = 12

12 + 8 = 20

2. 100 - 5 = 95

3. (45+7)÷(12÷3) + 9 x 2

First, calculate (45+7) = 52

Then, calculate (12÷3) = 4

Then, calculate 52 ÷ 4 = 13

Finally, calculate 13 + 9 x 2 = 13 + 18 = 31

4. 15 x 3 - 1 = 44

Explanation: First, perform multiplication: 15 x 3 = 45

Then, perform subtraction: 45 - 1 = 44

5. [(75-26)÷7] + [4 x (84 ÷ 12) ]

First, calculate (75-26) = 49

Then, calculate (49÷7) = 7

Next, calculate (84 ÷ 12) = 7

Then, calculate 4 x 7 = 28

Finally, calculate 7 + 28 = 35
