The selling price of an item is $600. After 6 months of not selling, it is marked down by 30% . After another 6 months of not se
Bingel [31]

The sale price after both markdowns will be $336

<em><u>Explanation</u></em>

The selling price of an item is $600. After 6 months of not selling, it is marked down by 30%

So, the marked down amount after 6 months =\$ 600*0.30= \$180

and the selling price after first 6 months will be: \$600-\$180=\$420

After another 6 months of not selling , it is further marked down by 20%. So, the marked down amount now = \$420*0.20=\$84

Thus, the final selling price after all markdowns =\$420-\$84=\$336

What is the solution for the equation 5/3b^3-2b-5=2/b3-2
irinina [24]

Answer:

Option C is correct.

Step-by-step explanation:

Given Equation:

\frac{5}{3b^3-2b^2-5}=\frac{2}{b^3-2}

To find: Solution of the Equation.

Consider,

5(b^3-2)=2(3b^3-2b^2-5)

5b^3-10=6b^3-4b^2-10

6b^3-5b^3-4b^2+10-10=0

b^3-4b^2=0

b^2(b-4)=0

b² = 0   ⇒ b = 0

b - 4 = 0 ⇒ b = 4

Therefore, Option C is correct.

I need some one to help me with this
Ahat [919]

y = 6x  - 2
You can see that each time x increases by 1, y increases by 5. This means that the coefficient of x is 5 (if you graphed it, the slope would be 5). To find what value to add at the end, you can look at what y is when x equals 0. In this case, that is -2 (on a graph, -2 would be the y-intercept).
