19b-(-10b)-(-2b)-(-3b)-20b = 14

14b=14 Simplify

b=1 Divide

You are posting a lot of these types of problems. Maybe the course you are taking is to difficult for you?

B=1 because all of these added together =14b, so 14 times 1= 14

Explain how to solve 2^x + 1 = 9 using the change of base formula log base b of y equals log y over log b. Include the solution
elena55 [62]

Answer:

x=2.170

Step-by-step explanation:

The given equation is 2^{x+1}=9.

We take logarithm of both sides to base 2 to get:

\log_2(2^{x+1})=\log_29

Apply the power rule of logarithms to get:

x+1=\log_29

We now apply the change of base formula:

x+1=\frac{\log_{10}9}{\log_{10}2}

x+1=\frac{0.9542}{0.3010}

x+1=3.1701

x=3.1701-1

x=2.1701

To the nearest thousandth, x=2.170

Noah wants to buy a skateboard that usually sells for $79.99. All merchandise is discounted by 12%. What is the total cost of th
beks73 [17]

Answer:

$74.36 sorry all i got

Step-by-step explanation:

First, we need to determine the sales price of the skateboard. The formula for find the discounted prices is:

Where:

is the sales price of the item: what we are solving for in this part of the problem.

is the regular price of the item: $79.16 for this problem.

is the discount rate: 12% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 12% can be written as  

12

100

Substituting and calculating  

gives

79.16

79.16

12

100

79.16

949.92

100

79.16

9.4992

69.6608

69.66

rounded to the nearest cent.

Now we can find the total price of the item with tax included. The formula for this is

#t = p + (p * r)

Where, this time:

is the total price: what we are solving for in this problem.

is the price of the item: it is the sales price of the item for this problem which is $69.66

is the tax rate: 6.75% or, using the same rule as in the formula above:  

6.75

100

Substituting and calculating  

gives:

69.66

69.66

6.75

100

69.66

470.205

100

69.66

4.70205

74.36205

74.36

rounded to the nearest cent.

Noah would pay a total cost (with the discount and after tax) of $74.36

Jeff buys a car for $28,000. the vehicle depreciates by 16% each year. Which of the following is the common ratio of the sequenc
Yanka [14]
Find the value of the car in the next year
value next year = (100% - 16%) × 28,000
value next year = 84% × 28,000
value next year = 84/100 × 28,000
value next year = 23,520
The value of the car in the next year is $23,520

Find the ratio
ratio = value of next year/value of recent year
ratio = 23,520 / 28,000
ratio = 0.84
The ratio is 0.84, it's the same with the percentage of value in the next year (84%)
