Flower: Anthony decides to decorate a ballroom with r= 3n + 20 roses, where n is the number of dancers. It occurs to Anthony that the dancers always come in pairs. That is, n=2p, where p is the number of pairs. What is r as a function of p?

Can anyone explain the process of how to answer this problem?

Answer:24

Step-by-step explanation:

The ratio of 6 to 4 is the same as the ratio of 36 to 24. This is found by setting up the ratios as fractions, setting them equal to each other, and then solving for the unknown.

The question is asking for an equivalent ratio to that of 6 to 4, using 36 as the first term. To do this, you need to determine what number 36 is in the same ratio. A ratio is a relationship between two numbers indicating how many times the first number contains the second. In our case, 6 is to 4 as 36 is to what?

To find the answer, you can set up the ratios as fractions and solve for the unknown. For example, the ratio of 6 to 4 is expressed as 6/4. Because we want a ratio that's equivalent, we say 6/4 = 36/x, where x is the unknown number, we need to find.

Solving for x involves arranging the equation to isolate x and then performing the algebraic operation that gives the value of x. This would be: 6/4 = 36/x -> 6x = 36×4 -> 6x = 144 -> x = 144/6 -> x = 24.

Therefore, the ratio of 6 to 4 is equal to the ratio of 36 to 24 in math.

Answer:

x=-10

Step-by-step explanation:

Answer:

x = -10

Step-by-step explanation:

I will assume that you meant:

(1/4)(8x-20)=6x - (x-25) = 5x + 25

If this is correct, let's remove the denominator 4 by multiplying all terms by 4:

(8x - 20) = 4(6x - x + 25), or

8x - 20 = 20x + 100

Consolidating the x terms on the right and the constants on the left, we get:

-120 = 12x, or x = -10

Step-by-step explanation:

Absolute values are always non-negative, so |-2.24| equals 2.24.

The absolute value of a number is its distance from zero on the number line, ignoring its sign. For -2.24, the distance from zero is 2.24 units.

This concept is useful in various mathematical calculations, such as finding the magnitude of a vector in physics or determining the error in measurements. In practical terms, it allows us to express distances, differences, or deviations without regard to direction. For example, if you are comparing temperatures, the absolute difference between -5°C and 8°C is 13°C, regardless of whether you are measuring an increase or decrease in temperature. This property makes absolute values valuable in many areas of mathematics, science, and everyday life.

Answer:

400 + 5x = 582 - 8x

14 weeks

Step-by-step explanation:

Set them both up in an equation ---> x = weeks

400 + 5x = 582 - 8x

Solve

13x = 182

x = 14

To determine how many weeks it will take for Chris and Ben to have the same amount in their bank accounts, we can set up and solve an equation based on their weekly deposits and withdrawals. After setting their equations equal to each other and solving for 'x', we find that it will take 14 weeks.

To determine how many weeks it will take for Chris and Ben to have the same amount in their bank accounts, we can set up an equation based on their weekly deposits and withdrawals. Let's represent the number of weeks as 'x'.

Chris's bank account balance can be represented by the equation: 400 + 5x

Ben's bank account balance can be represented by the equation: 582 - 8x

To find the number of weeks it takes for their balances to be equal, we can set their equations equal to each other and solve for 'x':

400 + 5x = 582 - 8x

Combining like terms and isolating 'x', we get:

13x = 182

Dividing both sides by 13, we find that x = 14.

Thus, it will take 14 weeks for Chris and Ben to have the same amount in their bank accounts.

Final answer:

To find the width of a rectangular poster with a perimeter of 124 inches and a length that is 10 inches longer than the width, set up the perimeter equation, solve for the width, and find that the width is 26 inches.

Explanation:

The student asks to find the width of a rectangular poster where the length is 10 inches longer than the width, and the perimeter is 124 inches.

Firstly, let's denote the width of the poster as w inches. Therefore, the length is w + 10 inches. The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.

We can set up the equation for the given perimeter:

2(w + 10) + 2w = 124

Simplifying the equation:

2w + 20 + 2w = 124

4w + 20 = 124

4w = 104

w = 26

The width of the poster is 26 inches.

Answer:

Each student get less than 1 cup of broth.

Step-by-step explanation:

We have been given that a  teacher divides the 5 cups of broth among 6 students. We are asked to determine the amount that each student will get would be more than or less than 1 cup of broth.

Since there are 5 cups of broth, so we can distribute them to 5 students each having one cup of broth.

As the teacher divides the 5 cups of broth among 6 students, therefore each student will get less than one cup that is [tex]\frac{5}{6}[/tex] of cup.

Step-by-step explanation:

The equation of a line in slope- intercept form is

To find c substitute ( [tex]\frac{2}{3}[/tex], 4) into the partial equation

4 = 2 + c ⇒ c = 4 - 2 = 2

y = 3x + 2 → A
