The answer you are looking for is -2.
To solve the equation given, 7 ÷ 2 - 4.5 · 3 + 8, you follow the rules of PEMDAS.
First, solve 7 ÷ 2 to get 3.5. This leaves the equation to say "3.5 - 4.5 · 3 + 8".
Next, multiply 4.5 by 3 to get 13.5. The equation would now say "3.5 - 13.5 + 8".
Then, you subtract 13.5 from 3.5. 3.5 - 13.5 = -10. The equation says "-10 + 8"
Finally, add 8 to -10 to get a final answer of -2.
I hope this helps!
