Chad owns twice as many cds as carlin owns. if you add 6 to the number of cds chad owns and then divide by 7, you get the number of cds bryce owns. bryce owns 30 cds. how many cds does carlin own?

Answers

Answer 1

An equation is formed of two equal expressions. The number of CDs owned by Carlin is 102.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the following points:

Chad owns twice as many CDs as Carlin owns. if you add 6 to the number of CDs chad owns and then divide by 7, you get the number of CDs Bryce owns. Bryce owns 30 CDs.

Let the variables represent the following numbers as shown,

CDs owned by Chad = M.Cds owned by Carlin = NCDs owned by Bryce = O

The number of CDs owned by Chad.

M = 2N ______(1)

The number of CDs owned by Carlin.

= N ________(2)

The number of CDs owned by Bryce.

O = (6+2N) / 7

And O = 30

30 = (6 + 2N) / 7 ________(3)

From (3), the value of N can be written as,

30 = (6 + 2N) / 7

Multiply both sides by 7

30 x 7 = 6 + 2N

210 = 6 + 2N

Subtract 6 on both sides.

210 - 6 = 6 + 2N - 6

204 = 2N

Divide both sides by 2.

102 = N

N = 102

Thus, the number of CDs owned by Carlin is 102.

A movie theater sells student tickets for $5 and adult tickets for $10. On Saturday night, 2,500 people go to the theater and ticket sales total $18,000. How many adults and children went to the theater on Saturday night? Which solution is reasonable? A) 2000 students and 1000 adults B) 1100 adults and 1400 students C) 3000 students and 0 adults D) 500 students and 1500 adults

Answers

The problem says that 2500 people went, out of all the answers choices which choice gives you the total of 2500 when you add the adults and children.

Answer is B because 1100 + 1400 = 2500

The reasonable solution is B) 1100 adults and 1400 students, as it satisfies both attendance and revenue criteria.

Consider a movie theater that sells student tickets for $5 and adult tickets for $10. On a Saturday night, 2,500 people attended the theater, and the total ticket sales amounted to $18,000. The goal is to determine the number of adults and students who attended, with multiple choices provided:

We can set up two equations to represent the information:

The total number of people who attended: S + A = 2500

The total ticket sales amount: 5S + 10A = 18000

Solving this system of equations gives the correct solution:

B) 1100 adults and 1400 students.

This solution satisfies both equations (S + A = 2500 and 5S + 10A = 18000). It is reasonable as it accounts for both students and adults attending, and the total revenue aligns with the given information. The number of students (1400) and adults (1100) adds up to the total attendance of 2500.

butch, harry, and nicky are playing a game. Harry has half as many points is butch. Nicky has 5 fewer points than Harry. Together, the three players have 31 points. How many points does Harry have?

Answers

Harry has 9 points. First, make some expressions to show what you know. I'll use the variables b, h, and n to represent the number of points each player has h = b/2 n = h - 5 b + h + n = 31 Substitute h - 5 for n in the 3rd expression b + h + h - 5 = 31 Now substitute b/2 for the h's in that expression b + b/2 + b/2 - 5 = 31 Now solve for b, first add the b terms together 2b - 5 = 31 Add 5 to both sides 2b = 36 Divide both sides by 2 b = 18 We now know that Butch has 18 points, so plug that value into the formula for Harry's points h = b/2 h = 18 / 2 h = 9 And we now know that Harry has 9 points.

PLEASE HELP!!!!! How does “rationalizing the denominator” use the form of 1?

Answers

"Rationalizing the denominator" of a number is exactly what its title implies: turning its denominator into a rational number.

For an example, let's take the fraction 1/√2. We call √2 irrational because it cannot be expressed as a ratio of two integers. Oftentimes when we have irrational numbers like √2 in the denominator, it helps to perform a little bit of algebraic manipulation on them to make the denominator rational. Here's where that "form of 1" comes in. Remember that, as a rational number, 1 can be expressed as n/n, where n is any number. We can use this fact to rationalize the denominator of 1/√2 by multiplying it by √2/√2, which is equivalent to 1.

When we multiply the two together, we get:

[tex] \frac{1}{\sqrt{2}}\cdot \frac{\sqrt{2}}{\sqrt{2}}= \frac{\sqrt{2}}{(\sqrt{2})^2}= \frac{\sqrt{2}}{2} [/tex]

Crucially, multiplying by 1 in the form of √2/√2 keeps the fraction's value the same, since 1 times any number just equals that same number. If we weren't multiplying but some form of 1, we'd change the number entirely, making the whole attempt at rationalizing the denominator pointless.

Quoting from interviews with government workers and bystanders who were hiding behind locked doors and had no police protection, appealing to the emotion of fear.Recreating images with vivid descriptions and concrete language of lone officers overwhelmed by crowds of people and beaten, appealing to the emotions of fear and empathy.Using nonaggressive language to address opposing views, showing empathy and attempting to convince others to support the author's position.Adhering to descriptive diction and employing sensory detail, creating a rhetorical effect.Refuting counterclaims and appealing to readers' logic and emotions, demonstrating fairness and advanced skill at persuasion.

The use of emotionally charged language reveals the emotions of fear, empathy, conviction, and persuasion in the document.

For which value of k will the roots of the equation 2x^2-5x+k=0 be real and rational numbers

Answers

The trick here is to find the discriminant, b^2-4ac, of the equation 2x^2 - 5x + k.
Here a=2, b=-5, and c=k.

So long as the discriminant is 0 or greater than 0, your roots will be real and rational numbers.

Thus, compute b^2-4ac: (-5)^2 - 4(2)(k)

Let this equal zero and solve for k: 25=8k; k=25/8.

So long as k is 25/8 or smaller, b^2-4ac will be 0 or greater, and the roots will be real and rational.

25/8 is the value of k will the roots of the equation 2x^2-5x+k=0 be real and rational numbers

What is quadratic equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

A quadratic equation has real roots when the discriminant is positive or zero (not negative).

b²-4ac≥0

b=-5, a=2, c=k

(-5)²-4((2.k)≥0

25-8k≥0

25≥8k

Divide both sides by 8

25/8≥k

k≤25/8

Hence, 25/8 is the value of k will the roots of the equation 2x^2-5x+k=0 be real and rational numbers

What are the coordinates for the x and y intercepts of the function 4y - 2x = 24?

Answers

For 4y, I believe the coordinates are (4,6) and the coordinates for 2x are (2,12). This is my best guess. Let me know if I'm wrong.

First, let's put this in Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
4y - 2x = 24 Add 2x to both sides
4y = 2x + 24 Divide both sides by 4
y = (1/2)x + 6
Now that we're in slope-intercept we can easily find the y and x intercepts/
b = 6, so the y-intercept equals 6. Plug zero in for x to confirm!

Now we plug 0 in for y to find the x intercept:
0 = (1/2)x + 6 Subtract 6 from both sides
-6 = (1/2) x Multiply both sides by 2
-12 = x
The x intercept is -12

In Conlusion:
x-intercept = -12
y- intercept = 6
