-4 = x/9 - 8

-x/9 = 4 - 8

-x/9 = -4

x = 4 * 9

x = 36

Total number of marbles : 3 + 8 = 11

8 are white.

Probability of picking a white one is 8/11

A) is 164 because 6 times 6 is 36. 500 - 36 is 164

d - 2 < -1 is how this inequality would be displayed.

However, we can solve for the value of d by treating this like a standard algebraic equation.

d - 2 < -1

Add 2 to both sides.

d < 1

The value of d is less than 1.

Let me know if you have any other questions.

Answer:

Given phrase,

a number d minus 2 is less than -1

∵ '-' is the sign of minus,

⇒ d minus 2 = d - 2

Also, '<' is the sign of less than,

⇒ d minus 2 is less than -1 = d - 2 < - 1

Hence, the required inequality would be,

[tex]d-2 < -1[/tex]

Now, by further solving,

Add 2 on the both sides of inequality ( additive property of inequality )

[tex]d < -1 + 2\implies d < 1[/tex]

⇒ d ∈ ( -∞, 1 )

[tex]\((21/2 \times 2 \ 3/4)^2\) is equivalent to \(\frac{13320.25}{16}\)[/tex]

Sure, let's simplify the expression [tex]\((21/2 \times 2 \ 3/4)^2\)[/tex] step by step:

1. [tex]\(21/2\)[/tex] can be simplified to [tex]\(10.5\)[/tex].

2. [tex]\(2 \ 3/4\)[/tex]can be written as an improper fraction: [tex]\(2 \ 3/4 = 8/4 + 3/4 = 11/4\)[/tex].

Now, the expression becomes [tex]\((10.5 \times 11/4)^2\)[/tex].

3. Multiply [tex]\(10.5\) by \(11/4\): \(10.5 \times 11/4 = 115.5/4\)[/tex].

Now, the expression is [tex]\((115.5/4)^2\)[/tex].

4. Square the fraction: [tex]\((115.5/4)^2 = (115.5^2)/(4^2)\)[/tex].

5. Calculate the numerator and denominator separately: [tex]\(115.5^2\)[/tex] in the numerator and [tex]\(4^2\)[/tex] in the denominator.

[tex]\[ \text{Numerator: } 115.5^2 = 13320.25 \][/tex]

[tex]\[ \text{Denominator: } 4^2 = 16 \][/tex]

6. The final result is [tex]\(\frac{13320.25}{16}\)[/tex].

Now, you can simplify this fraction by dividing the numerator by the denominator:

[tex]\[ \frac{13320.25}{16} \div 1 = \frac{13320.25}{16} \][/tex]

Let 1 piece = X

The 2nd piece would be X + 2 feet

Add:

x +x+2 = 26 feet

2x +2 = 26 feet

Subtract 2 from each side:

2x = 24

Divide both sides by 2:

x = 24 / 2

X = 12

One piece is 12 feet the other piece is 14 feet.

Answer:

x + y = 75.9 + 2.65 = 78.55

Step-by-step explanation:

To solve x + y given that x = 75.9 and y = 2.65. We will simply substitute the value of x in the equation with it value which is 75.9 and substitute the value of y in the equation with it value which is 2.65.

Therefore we have x + y to be

x+y

= 75.9 + 2.65

= 78.55

Therefore x + y = 78.55

The cost per ounce of the first bottle is $0.415 and the second bottle is $0.699.

The first bottle has the better deal because if you were to have 14 ounces of the first type of shampoo, it would only cost $5.81

Cost per ounce is:

To find the cost per ounce for each bottle, use the formula:

= Total cost / number of ounces

6 ounce bottle:

= 2.49 / 6

= $0.42 per ounce

14 ounce bottle:

= 9.79 / 14

= $0.70 per ounce

The 6 ounce bottle is therefore the better deal.

Answer:

D. 26.75 pounds/minute

Step-by-step explanation:

For calculate unit rate that reflects the speed of the processor we can use the following equation:

[tex]Speed = \frac{Total Pounds}{RequiredTime}[/tex]

Taking into account that the answers are in pounds per hour and pounds per minute, we re going to calculate the speeds in booth units.

1. Speed in Pounds per hours: Replacing Total Pounds by 4,815 and Required time by 3 hours, we get:

[tex]Speed = \frac{4,815Pounds}{3 Hours}=1,605 Pounds/hour[/tex]

2. Speed in Pounds per minute: Every hour have 60 minutes, the 3 hours have 180 minutes, so replacing Total Pounds by 4,815 and Required time by 180 minutes, we get:

[tex]Speed = \frac{4,815Pounds}{180 Hours}=26.75 Pounds/hour[/tex]

So, chosen the rate that appear in the answers, we can say that the correct answer is D. 26.75 pounds/hours.

i think that you would just take 23/4=$5.75

so take 6 times 5.75 and you should get $34.5

To answer this question, we first need to determine the unit cost (cost per t-shirt).

Step 1: Find the unit cost
Alicia bought 4 T-shirts for a total of $23.00. To calculate the cost per T-shirt (the unit rate), we need to divide the total cost by the number of T-shirts.

So, $23.00 (total cost) divided by 4 (number of T-shirts) equals $5.75. Thus, the unit cost of one T-shirt is $5.75.

Step 2: Calculate the cost for 6 T-shirts
Now that we know the unit cost, we can find out how much 6 T-shirts will cost. To do this, we multiply the unit cost by the number of T-shirts.

So, $5.75 (cost per T-shirt) times 6 (number of T-shirts) equals $34.50.

Therefore, it would cost $34.50 for 6 T-shirts, given the unit rate.

The approximate population of South Dakota in 2010 after a 7.9% increase from the 2000 population is 814,477 people.

To find the population of South Dakota in 2010, we need to calculate the increased population based on the given percentage increase. We are provided with a population of 754,844 in 2000 and an increase of 7.9% for 2010.

Here is the step-by-step calculation:

Multiply the population of 2000 by the increase percentage (converted to a decimal):

754,844 x 0.079 = 59,632.68.

Add this increase to the 2000 population to get the 2010 population:

754,844 + 59,632.68 = 814,476.68.

Therefore, the approximate population of South Dakota in 2010 is 814,477 people (rounded to the nearest whole number).

Let x is the days and the y is the height of the plant.

Let the change between x and y is linear.

So, the relation between x and y will take the form ⇒ y = ax + b

where a and b are constants.

At x = 30 ⇒ y = 18  ⇒⇒⇒  ∴ 18 = 30 a + b   → (1)

The measure of angle ∣4 is 250 degrees. The measure of angle ∣A is 67 degrees.

To find the measure of angle ∣4, we can use the fact that angles around a point add up to 360 degrees.

We know that ∣1 is 45 degrees and ∣3 is 65 degrees.

To find ∣4, we can subtract the sum of angles ∣1 and ∣3 from 360 degrees.

Therefore, ∣4 = 360 - (∣1 + ∣3) = 360 - (45 + 65) = 360 - 110 = 250 degrees.

To find the measure of angle ∣A, we can use the fact that the sum of the angles in a triangle is 180 degrees.

We know that ∣B is 90 degrees because it is a right angle.

Therefore, ∣A + ∣B + ∣C = 180 degrees.

Substituting the given values, we get (3x - 8) + 90 + (x - 2) = 180. Simplifying the equation, we get 4x + 80 = 180.

Solving for x, we get x = 25.

Substituting x back into the equation for ∣A, we get ∣A = (3(25) - 8) = 67 degrees.

Answer: The statement is [tex]\frac{AD}{DB} +1=\frac{CE}{EB}+1[/tex] and the reason is add 1 both sides.

Explanation:

The given equation is [tex]\frac{AD}{DB} =\frac{CE}{EB}[/tex].

We know that according to the addition property the equation x=y and x+c=y+c are equivalent equations, where c is a constant.

So we can add 1 both sides in the given equation.

[tex]\frac{AD}{DB} +1=\frac{CE}{EB}+1[/tex]

Now we can take LCM and we get,

[tex]\frac{AD+DB}{DB} =\frac{CE+EB}{EB}[/tex]

The plane travels at 60 mph and the wind is blowing at 20 mph.  

By setting up and solving a system of equations, we find that the speed of the plane in still air is 63 mph and the speed of the wind is 21 mph.

To answer this question, you first need to set up equations to represent the speed of the plane and the speed of the wind. You can denote the speed of the plane in still air as 'p' and the speed of the wind as 'w'. The plane's speed with the wind (going to Phoenix) is represented by p+w and against the wind (coming back) is p-w.

For the trip to Phoenix, you know that distance = speed * time. That gives us the equation 1176 = 14(p+w). After simplification, we obtain the equation, p+w = 84.

For the return flight, our equation is 1176 = 28(p-w). On simplification, we find the equation p-w = 42.

Now you have a system of equations that you can solve: p+w = 84p-w = 42. Solving these equations together, you find that the speed of the plane (p) in still air is 63 mph, and the speed of the wind (w) is 21 mph.
