a) 20
b) 21
c) 22
d) 23

Answer 1

We have:

`3(8-4)+2\cdot5.5`

`3(4)+2\cdot5.5`

`12+2\cdot5.5`

`12+11`

`\boxed{23}`.

So, the answer is d) 23.

Answer 2

The simplified value of the expression 3(8-4)+2×5.5 is 23, which is found by performing operations inside the parentheses, then multiplying and adding as per PEMDAS.

Step-by-step explanation:

To find the simplified value of the expression 3(8-4)+2×5.5, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

1. Solve the operation inside the parentheses: 8-4 which equals 4.
2. Multiply the result by 3: 3×4 which equals 12.
3. Perform the multiplication of 2 and 5.5: 2×5.5 which equals 11.
4. Add the results of steps 2 and 3: 12+11 which equals 23.

Therefore, the simplified value of the expression is 23, which corresponds to option d).
