Answer: <em>x=8</em>
Step-by-step explanation:
<em>3(x-4)=12</em>
<em>Distribute the 3 into the parathesis'</em>
<em>3x-12=12</em>
<em> +12 +12 on each side</em>
<em>3x=24</em>
<em>Divide by 3 on each side</em>
<em>x=8</em>

Answer:
What?
Step-by-step explanation:
Answer:
Add the exponents and keep the bases the same. Then find the reciprocal and change the sign of the exponent
Step-by-step explanation:
When multiplying exponents with the same base number, you can add the powers. (If it was dividing, you would subtract the powers). You would then get
.
- 2³ = 8,
- 2² = 4,
- 2^1 = 2,
- 2^0 = 1
The pattern is to divide by 2. This means that
would be 1 ÷ 2 which is 1/2.
Tip: Any number to the power of -1 means to give its reciprocal.
