Answer:
D. 95 + 47 + 5.12 12 ÷ 4 ≠ 4 ÷ 12.
Step-by-step explanation:
(70 +30) + 72 B. 21 + (-14) + (-53) O C. 67 +1 - 18. So 12÷4≠4÷1/4 + 3/4 + 2. C. 20 + 80 + (-11)
3/4 because if you multiply 4 to 3 you'll get 12 and multiply it by 4 then you'll get 16 which will look like 12/16. Compare that. Ex: 12/16 > 11/16
The answer is b because all you have to do is just subtract if I am wrong so sorry
Answer:
1. x = 15
2. x = 26
3. x = 7.6157731059 (you can round this answer to 8 or 7.6)
4. x = 11.7
5. x = 25
6. x = 1.4
7. x = 22.5
8. x = 38.4
9. x = 10.3 v = 5.8
For some of them, I had to use estimation.
I used this formula : a^2 + b^2 = c^2
