Answer:

b = 12

Step-by-step explanation:

2/3 b - 1/3 b + 12 = 16

or, 2b/3 - b/3 + 12 = 16

or, 2b -b/ 3 + 12 = 16

or, 2b - b = 16 - 12

or, b = 4 × 3

therefore, b = 12

Answer: d) b = 12

2/3.b - 1/3.b + 12 = 16

Answer:

Assuming that the last four numbers are answer choices, your answer would be 11

Step-by-step explanation:

9/11 rounds up to 1, 1 + 18 = 19

3/8 rounds down, so you only have 8 for that one

Which number is equal to 10 Superscript negative 3? –1,000 –30 0.001 0.003
Karolina [17]

<u>Given</u>:

The given expression is 10^{-3}

We need to determine the equivalent number.

<u>Equivalent expression:</u>

To determine the equivalent number, let us solve the expression 10^{-3}

Thus, let us apply the exponent rule a^{-b}=\frac{1}{a^{b}} , we get;

10^{-3}=\frac{1}{10^{3}}

Also, the term 10³ can be written as 10^{3}=1000

Thus, we get;

\frac{1}{1000}

Dividing, we get;

0.001

Hence, the equivalent number is 0.001

Hence, Option c is the correct answer.
