A. 18+2 = 20 abs 18-2= 17
Answer:
19
Step-by-step explanation:
Matt ended up with 26.
We reverse the steps he did to get the original number that both people thought of.
26 / 2 = 13
13 - 7 = 6
6 is the original number.
Tikka did the same operations but in the reverse order so...
6 X 2 = 12
12 + 7 = 19
Anything greater than 4 but less than 9
