Answer:
4x-20
Step-by-step explanation:
you put the x's together and since its negative,you can make it -20 instead of +-20
67 because 24 isnot 50 yet so you would keep 67 how it is but if it was 50 or more then you would round it up to 68
28.26 is closest to 28 so you round 28.26 to 28, not 29.
Answer:
It is no real solutions
Step-by-step explanation:
so you would multiply 3 by the sum of 24 and 9...
3(24+9)=3(33)=99
