Solve<br> -21 = -9 + 2/3b

Svet_ta [14]

Final Answer: $b = -18$

Steps/Reasons/Explanation:

Question: Solve $-21 = -9 + \frac{2}{3}b$ .

<u>Step 1</u>: Simplify $\frac{2}{3}b$ to $\frac{2b}{3}$ .

$-21 = -9 + \frac{2b}{3}$

<u>Step 2</u>: Regroup terms.

$-21 = \frac{2b}{3} - 9$

<u>Step 3</u>: Add $9$ to both sides.

$-21 + 9 = \frac{2b}{3}$

<u>Step 4</u>: Simplify $-21 + 9$ to $-12$ .

$-12 = \frac{2b}{3}$

<u>Step 5</u>: Multiply both sides by $3$ .

$-12$ × $3 = 2b$

<u>Step 6</u>: Simplify $-12$ × $3$ to $-36$ .

$-36 = 2b$

<u>Step 7</u>: Divide both sides by $2$ .

$-\frac{36}{2} = b$

<u>Step 8</u>: Simplify $-\frac{36}{2}$ to $-18$ .

$-18 = b$

<u>Step 9</u>: Switch sides.

$b = -18$

Answer:

2x = y

Step-by-step explanation:

As you can see in the table, y = 2x, this is proven by the fact that if you divide any value in the y of the table by 2 you will get its corresponding x value, proving that 2x = y is the function that is used to represent this table's value.

Please, help me on this question, guys! I know the answer for (a) so I'll write down, too. For (b) I tried "$89,000 because that

Alexeev081 [22]

Let x be a random variable representing the price of a Congo-imported black diamond. Let the higher price be p. Then,
P(x < p) = P(x < (p - mean)/sd) = P(x < (p - 60,430)/21,958.08) = P(z < 2)
Therefore,
(p - 60,430)/21,958.08 = 2
p - 60,430 = 2 x 21,958.08 = 43,916.16
p = 34,916.16 + 60,430 = 104.346.16

Therefore, The required price is $104,346.16
