Answer:

b=-5

Step-by-step explanation:

Divide by -9 to eliminate the -9 on -9b

(Since -9b is the same thing as -9 times b we can use the inverse of multiplication which is division to eliminate the -9 from b but we need to do it on both sides to make it balance)

-9b/-9=45/-9

b=-5

Answer:

$324.46

Step-by-step explanation:

$405 × 0.05= $20.25 is how much it is marked up if the original price is $405.

$405 +$ 20.25 = $425.25 is the new total of the clarinet

Now 30 % of $425.25... $425.25×0.30= $127.58 is what 30% is.

You have to subtract th $127.58 from $425.25 to get the discounted price.

$425.25 - $127.58 = $297.67

Next you have to calculate for the 9% and add it to the discounted price.

$297.67 × .09 = $26.79

$297.67 + $26.79= $324.46

$324.46 is the cost of the clarinet.

Answer:

At the point where x = 2.

Step-by-step explanation:

First find the derivative which gives us the gradient of the tangent at any point on the curve:

y = 5x^2 - 16x

y' = 5*2 x^(2-1) - 16 x(1-1)

y' = 10x - 16.

y' is the gradient at point of coordinate x.

So when the gradient = 4:

4 = 10x - 16

10x = 20

x = 2.

x=2

Answer: 60 miles

Step-by-step explanation:

On a map, Indy and Fort Wayne are 19 centimeter apart while Kokomo and Indy are 9.5 cm apart on the map.

In real life, Indy and Fort Wayne are actually 120 miles apart, the distance between Indy and Kokomo in real life would then be:

= 9.5 × 120/19

= 120/2

= 60 miles

Indy and Kokomo are 60 miles apart in real life.

Step-by-step explanation:g-g5

The rate of interest will be 0.35.

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

[tex]CI = P(1+\frac{r}{n}) ^{nt} -P[/tex]

and, the Amount is given by

[tex]A = P(1+\frac{r}{n} )^{nt}[/tex]

Where,

A is amount

P is principal

r is rate of interest

n is number of times interest is compounded per year

t is time

According to the given question

Principal, P = $210

Amount, A = $250

Time, t = 5 years

n = 1

Therefore, the interest rate is given by

Amount = [tex]P(1+\frac{r}{n}) ^{nt}[/tex]

⇒[tex]250 = 210(1+\frac{r}{1}) ^{5}[/tex]

⇒[tex]\frac{250}{210} =(1+r)^{5}[/tex]

⇒[tex]1.19 = (1+r)^{5}[/tex]

⇒[tex]\sqrt[5]{1.19} = 1+r\\[/tex]

⇒ 1.035 = 1 + r

⇒ r = 1.035 - 1

⇒ r = 0.35

Hence, the interest rate is o.35.

Answer:

12

Step-by-step explanation:

2x + 24° = 4x ( being vertically opposite angles)

4x - 2x = 24°

2x = 24°

x = 24° / 2

x = 12°

Answer:

In 11 months, the number of DVDs sold and Blue-Ray discs sold will be same, 791 of each.

Step-by-step explanation:

In the equation d = 923-12t, substitute 505+26t (from the second equation) for 'd'. We get

505 + 26t = 923 - 12t

-505 + 12t   -505 + 12t

38t     =       418

t=11

d = 923-12(11) = 791

d = 505+26(11) = 791

After 11 months, selling 791 of each.

Answer:

The solution set of an inequality is < (less than) or > (greater than) to compare two or more numbers. Example 12 > - 10.

Step-by-step explanation:

When comparing two numbers, like 5 and 8, you probably recognize that the number 5 is less than the number 8. You probably also realize that the number 8 is greater than the number 5. In math, we use the inequality symbols < and > to compare two or more numbers.
