I believe the answer you are looking for is 2.
The answer could be 45 but I'm not entirely sure
So what you can do is take 49 and divide it by 2 cause times is multiplication so if you take 49 and divide that by 2 you would get 24.5. Now if you plug so like 24.5 · 2 would would get 49.

<span>add 13.3 + (–7)
= 13.3 - 7 = 6.3
</span>Subtract.
<span>–56 – (–27.07)
</span>= -56 + <span>27.07
= -28.93
</span>simplify
<span>14- (-8)+5 -(-10)
</span>= 14 + 8 + 5 + 10
= 37
