This is your perfect answer
Answer:
3-7 is negitive 4 in your answer it's 3-7 = -4
Step-by-step explanation:
It's negitive four because if you subtract you will get 4 but since it's other way around. And if you do It, it will say that even if there is no negitive sign it won't change the problem because it's still the same problem.
1) 3 - 7
2) there are 3 ways to do this to get the answer:
1) 3/7
2) 7 + 3 - 4 + 3
3) now 7 + 3 is ten - 7 is 3 + 4 is 7, so then if you do 3 - 7 you get negitive four
4) now check your answer by subtracting 3 and 7
5) then you get -4
btw: ( hope this helped :) )
It'd be A since dividing on a negative coefficient results flipping the sign of the inequality and results in a different impact
