Evaluate [(40 + 5) − 32] ÷ 9 ⋅ 2

2.89

Step-by-step explanation:

40+5 is 45

then subtracting 32 from 45 would give you 13.

then 13/9 is something like 1.445

then you multiply by 2 and get 2.89

6/20

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
