Determine whether the two questions are equivalent. If so, name the property that is applied. 54 - (30 - 8) and (54-30) - 8
Sphinxa [80]

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

3/2 (6 - 18x) &gt; 12<br> Solve
Ivanshal [37]

Answer:

x is less than 1/9

Step-by-step explanation:

Distribute the 3/2 to the (6-18x), which gives you 9-27x is greater than 12. Subtract the 9 over, which gives you -27x is greater than 3. Divide both sides by -27, but when you divide by a negative, you have to flip the sign, so finally, you get x is less than 1/9.
