Answer:
5x + 11
Explanation:
3(x + 7) + 2x − 10

3x + 21 + 2x − 10
<u>Combine Like Terms</u>
3x + 21 + 2x − 10
(3x + 2x) + (21 − 10)
= 5x + 11
Answer:
The two equations are not equivalent and no property is used.
Step-by-step explanation:
54 - (30 - 8) ... (i)
(54 - 30) - 8 ... (ii)
Solving (i) and applying PEMDAS:
We open the brackets first;
54 - 30 + 8 = 54 + 8 - 30 = 32
Solving (ii) and applying PEMDAS:
We open the brackets first;
54 - 30 = 24
24 - 8 = 16
