Solve -21 = -9 + 2/3b

Svet_ta [14]

Final Answer: $b = -18$

Steps/Reasons/Explanation:

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

Step 1: Simplify $\frac{2}{3}b$ to $\frac{2b}{3}$ .

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

Step 2: Regroup terms.

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

Step 3: Add $9$ to both sides.

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

Step 4: Simplify $-21 + 9$ to $-12$ .

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

Step 5: Multiply both sides by $3$ .

$-12$ × $3 = 2b$

Step 6: Simplify $-12$ × $3$ to $-36$ .

$-36 = 2b$

Step 7: Divide both sides by $2$ .

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

Step 8: Simplify $-\frac{36}{2}$ to $-18$ .

$-18 = b$

Step 9: Switch sides.

$b = -18$

the original price for a set of golf clubs is $500 at the beginning of the seasons the price was marked up by 20% at the end of

Blizzard [7]

Answer: The final price is less than the original

Step-by-step explanation:

Let us break this down a bit.

The original price is $500

-> At the beginning, the price was marked up by 20%

-> At the end, the price at the beginning of the season is marked down by 20%

We are solving for: "How does the final price compare with the original price of $500"

First, we will find the price at the beginning.

-> Please note a percent divided by 100 becomes a decimal

20% / 100 = 0.2

$500 * 0.2 = $100

$500 + $100 = $600

Now, we will find the price at the end.

$600 * 0.2 = $120

$600 - $120 = $480

The final price is less than the original price of $500.
