A $90 flannel shirt is on salle for 30% less for fall shoppers. What is the sale price of the warm winter flannel shirt?

The number of solution the equation 4x - 5 (2x + 1) = 6x + 1 have is one.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

4x - 5 (2x + 1) = 6x + 1

4x - 10x - 5 = 6x + 1

-6x - 5 = 6x + 1

-5 - 1 = 6x + 6x

-6 = 12x

x = -6/12

x = -1/2

This means,

The equation has one solution.

Thus,

The equation has one solution.

The lower quartile value is 13 and the upper quartile value is 27.

What is a Quartile?

A quartile divides the data set into four equal halves, that is, each set has an equal number of terms. The quartiles are given by Q₁(the lower quartile value), Q₂ (the median), Q₃ (the upper quartile value).

We first arrange the data set in ascending order. Here, the data set is already in ascending order, that is, 10,11,13,18,19,21,22,25,27,30,32.

So we will divide the above set into two equal halves. As the given set has 11 terms,

So the median is [tex]\frac{n+1}{2}[/tex] where n is the number of terms.

We have n=11

⇒ Median= [tex]\frac{11+1}{2}[/tex] th term

                = 6th term

⇒ Median= 21

Now the data to the left side of the median value will give the lower quartile and the data to the right will give the upper quartile.

The data to the left of median value 21 is 10,11,13,18,19.

The median value of this data will give the lower quartile value.

Median = [tex]\frac{5+1}{2}[/tex]th term= 3rd term

              =13

⇒Lower quartile is 13.

The data to the right of the median value 21 is 22,25,27,30,32

The median value of this data will give the upper quartile value.

Median = [tex]\frac{5+1}{2}[/tex]th term= 3rd term

             = 27

⇒Upper quartile is 27.

The correct answer is lower quartile= 13, upper quartile = 27

Answer:

Step-by-step explanation:

Answer: it is 0

Step-by-step explanation:

[5.5+(-2.3)] + (-5.5+2.3)

We can multiple (-5.5+2.3) by -1 so that it equals the first expression

[5.5+(-2.3)] + (-1)[5.5+(-2.3)]

Then, we change the + to -

[5.5+(-2.3)] - [5.5+(-2.3)]

since we are subtracting the same value, the answer is 0.

Answer:

The area is approximately 201.06

Step-by-step explanation:

If you use the equation pi r^2, then we will get the answer. Since the diameter is double the radius, we should know that the radius is 8ft. Then we do the math and get the answer above.

Answer: A≈201.06ft²

Step-by-step explanation:

How to Calculate Diameter?

Diameter = Circumference ÷ π (when the circumference is given)

Diameter = 2 × Radius (when the radius is given)

Diameter = 2√[Area/π] (when the area is given)

Answer:

a) The new balance in your checking account is -$12.58 - $30.72 = -$43.30.

b) After the bank charges a $25 fee for overdrafting, the balance in your checking account will be -$43.30 - $25 = -$68.30.

c) To bring your account balance back up to $0 after the fee, you will need to deposit $68.30.

Step-by-step explanation:

Answer:

First, you subtract the 30.72 from the -12.58 which is -43.03 which is therefore how much you have in your account. Then we subtract another 25 for the fee. -68.03 Is how much you have after paying the fee.

Therefore, to get to 0, you need to pay 68 dollars and 3 cents.

Answer:

The total number of students in the student body is 110. The part is 88 students, the whole is 110 students, and the percent is 80%.

Step-by-step explanation:

We can divide both sides of the equation by 43 to solve for x:

90x / 43 - 47y / 43 = -49 / 43

x = -49/43

We can substitute this value for x back into either of the original equations to find y. Let's substitute it into the first equation:

-5x + 3y = -6

(-5 * -49/43) + 3y = -6

y = (-6 + 5 * 49/43) / 3

y = 17/43

The solution to the system of equations is (x, y) = (-49/43, 17/43).

To check our solution, we can substitute the values we found for x and y back into the original equations and see if they hold true.

In the first equation, -5x + 3y = -6, substituting the values we found for x and y gives us:

(-5 * -49/43) + (3 * 17/43) = -6

This simplifies to -6 = -6, which is true, so the solution holds for this equation.

In the second equation, 9x - 4y = 1, substituting the values we found for x and y gives us:

(9 * -49/43) - (4 * 17/43) = 1

This simplifies to -1 = -1, which is true, so the solution holds for this equation as well.

Therefore, the solution (x, y) = (-49/43, 17/43) is correct.
