Ответ:
to get this just do the problem backwards from 10 witch you would add .5 to get 10.5 and then multiply by 2 to get 21 then add .5 again to get 21.5 then you multiply it again by 2 to get the answer of 43
hope this helps GL
Ответ:
B (if that sign is x + 4)
C (if that sign is x ÷ 4)
Step-by-step explanation:
We know that x is definitely less than the other value, and cannot possibly be equal to the other value, as it's x + 4, so the answer is B.
It's the other way round if it's x ÷ 4 and the answer will be C.
hopefully I interpreted this question the right way!
