Choose 1 answer:
47 + 2.5
-2.5 - 7
7+ (-2.5)
2.5 + 7


Sagot :

Answer: none
-7-(-2.5) in the calculator is -4.5
Which would mean none were equivalent, but if i do it by hand then the answer would be -17.5; again none would be equivalent.
But the closest one is -2.5-7, because it equals 4.5 rather than -4.5
