Answer:
9.4
Step-by-step explanation:
pi = 3.1415...
3.1415*3 = 9.4
Start by writing -3x-5=16. You can add 5 to both sides since the inverse operation of negative is adding positive. You will then get 16+5=21. Then you will get -3x=21. Divide by -3 on both sides. -3x/-3. 21/-3=-7 x=-7. Now check your answer -3(-7)=21-5=16. Checks out. Hopefully this helps!
3.5 divided by 10? maybe i'm not sure.
The answer is 4...... More than positive.
