Answer:

<h2>x = 21</h2>

Step-by-step explanation:

8+\dfrac{x}{3}=15\qquad\text{multiply both sides by 3}\\\\(3)(8)+3\!\!\!\!\diagup^1\cdot\dfrac{x}{3\!\!\!\!\diagup_1}=(3)(15)\\\\24+x=45\qquad\text{subtract 24 from both sides}\\\\24-24+x=45-24\\\\x=21

Are these correct? If not please help me write the correct answer.​
Keith_Richards [23]

Answer:

Mostly correct

For Q3, you are doing great, you remembered that negative numbers can happen if the exponent is an odd number.

For Q4, I think you were confused with the fractions,

4(i)

(\frac{2}{3} )^{4} = (\frac{2^{4}}{3^{4}}) = (\frac{16}{81}) =0.198

4(ii) is also wrong but I'll let you try to fix it yourself following what I given you for 4(i). You should get 1/64

Hope this helps!
