X=13; do you need the work? Also for future reference symbolab.com is where I get all my answers.
To do this you want to first multiply 28 by 0.15. This will give you $4.20. You have to give a $4.20 tip. The total cost would be the lunch and the tip added together. It would give you a final total of $32.20.
Answer: Choice A
Set the radicand (stuff under the radical) greater than or equal to 0. Solve x+11 >= 0 for x to get x >= -11
The answer is B. There are 12 line segments
9a + (9t+27)=x
To write it another way you could flip the numbers around:
(9t+27)+9a=x
Or flip the variable to the other side.
x=9a + (9t+27)
Any way you put the numbers as long as x is on the either side, you will get the same answer.
Hope this helps!
