Marco has $38.43 dollars in his checking account. His checking account is linked to his amazon music account so he can buy music. The songs he purchases cost $1.29. Part 1- write an algebraic expression to describe the amount of money in his checking account in relationship to the number of songs he purchased. Part 2- Describe what the variable represents in the situation

3x+5(4x-6)-8=3x-14

Step-by-step explanation:

Cancel out the terms on both sides of the equation. (3x)

5(4x-6)-8=-14

Distribute 5 through the parentheses.

20x-30-8=-14

Calculate the difference.

20x-38=-14

Move the constant to the right-hand side and change its sign.

20x=-14+28

Calculate the sum.

20x=24

Divide both sides of the equation by 20.

x=6/5, 1.2, or 1 1/5

Answer:

x=6/5, 1.2, or 1 1/5

Step-by-step explanation:

Given:

Patio drawing of 4.25 in by 2.5 in

Scale of Patio to its drawing = 4ft to 1 in

Requires:

Area of actual Patio

SOLUTION:

Area of actual Patio = area of a rectangle = length × width

Given a scale drawing of 4ft to 1 in, therefore:

Length of actual Patio = 4.25 × 4 = 17 ft

Width of actual Patio = 2.5 × 4 = 10 ft

Therefore:

Area of actual Patio = 17 ft × 10 ft = 170 ft²

Answer:

170ft

Answer: 7.0%

Step-by-step explanation:

The probability of rolling a sum of 14 is 7.0% because 15/216 = 7.0%

The probability of rolling a sum of 14 is  [tex]\frac{1}{72}[/tex]    or  0.014.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Formula of probability

Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex]  

According to the question

rolling a sum of 14

As the maximum sum of two dice is 6+6 = 12

Therefore ,

we will take 3 dices

Now ,

As each dice have 6 different digits and can be repeated

i.e

Total outcomes = 6 * 6 * 6 = 216  

Favorable outcome :

(6,6,2) or (2,6,6) or (6,2,6) = 3 ways

Now,

By using the formula of probability

Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex]  

Substituting the value in the formula

Probability(Event) = [tex]\frac{3}{216}[/tex]

Probability(Event) = [tex]\frac{1}{72}[/tex]    or  0.014

Hence, the probability of rolling a sum of 14 is  [tex]\frac{1}{72}[/tex]    or  0.014

Answer:

  A.  x = 5 or 7

  B.  these are zeros of the quadratic

Step-by-step explanation:

A) To factor this equation, we look for factors of +35 that have a total of -12. We know that ...

  35 = (-1)(-35) = (-5)(-7)

The latter factor pair has a total of -12, so we can use those in the binomial factors:

  (x -5)(x -7) = 0

The solutions are the values of x that make these factors be zero:

  x = 5   or   x = 7

__

B) The graph of the quadratic on the left of the equal sign is shown in the attachment. The solution values are the values of x where that graph crosses the x-axis, where the quadratic is equal to 0. This should come as no surprise, since we're solving the equation x^2 -12x +35 = 0.

If I understand correctly, I'm guessing you mean which 100,000s(ex.100,000) so it would be between 100,000 and 200,000

185,104 is between 100,000 and 200,000.

The hundred thousands are:

The number 185,104 is higher than the first 100,000.

Answer: 0.0010

Step-by-step explanation:

Given the following :

Population Mean(m) = 4.2 years

Sample mean (s) = 3.9

Standard deviation (sd) = 0.6

Number of samples (n) = 38

Calculate the test statistic (z) :

(sample mean - population mean) / (sd / √n)

Z = (3.9 - 4.2) / (0.6 / √38)

Z = (- 0.3) / (0.6 / 6.1644140)

Z = -0.3 / 0.0973328

Z = - 3.0822086

Z = - 3.08

From the z table :

P(Z ≤ - 3.08) = 0.0010
