Answer:

x = 25

Step-by-step explanation:

You would need to start by creating an equation.  X would represent the numbers of weeks.

500 + 30x = 750 + 20x

Now get the numbers on one side.  To do this subtract 500 form each side.

30x = 250 + 20x

Next, get the variables to one side.  This can be done by subtracting 20x from each side.

10x = 250

Finally divide by 10 to get the variable by its self.

x = 25

Hope this helps.

After 25 weeks, Collin and Kamryn have the same amount of

money in their accounts.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let's suppose the after x weeks, Collin and Kamryn have the same amount of money in their accounts:

Then we can frame a linear equation as per the problem:

Collin's amount of money  = 500 + 30x

Kamryn amount of money = 750 + 20x

500 + 30x = 750 + 20x

10x = 250

x = 25

Thus, after 25 weeks Collin and Kamryn have the same amount of

money in their accounts.

Answer:

She is not correct

x = -9

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180° therefore if you add all three angles in this triangle it must add up to 180°

50 - 5x + 5 - 4x + 17 - 3x = 180 add/subtract the like terms

72 - 12x = 180

- 12x = 108 divide both sides by 12

-x = 9

x = -9

Answer:

Marcos had 6 nickel coins and 9 quarter coins.

Step-by-step explanation:

We are given the following in the question:

Let x be the number of nickel coins and y be the number of quarter coins.

Marcos had 15 coins in nickels and quarters.

Thus, we can write the equation:

[tex]x + y =15[/tex]

He had 3 more quarters than nickels. We can write he equation,

[tex]y = x + 3[/tex]

Solving the two equations, we get,

[tex]2y = 18\\y = 9\\x + 9 = 15\\x = 6[/tex]

Thus, Marcos had 6 nickel coins and 9 quarter coins.

The solution to the system of equations representing Marcos's coins is x = 6 and y = 9. Hence, Marcos had 6 nickels and 9 quarters.

This question pertains to creating and solving a system of equations in mathematics. Given Marcos had 15 coins in nickels and quarters and considering the information that he had 3 more quarters than nickels, two equations can be formed from this. The first equation sets up the total number of coins: x + y = 15. The second equation sets ups the difference in quantity of each coin: y = x + 3.

To find the solution, substitute the second equation in for y in the first equation. This gives: x + (x + 3) = 15. Solve the equation and find x = 6. Furthermore, using x in our second equation, we get y = 6 + 3 = 9. Therefore, Marcos had 6 nickels and 9 quarters.

Final answer:

To determine the maximum number of adults and children that can attend the play without exceeding the bus capacity of 40 people and the $400 budget, set up and solve a system of equations representing the capacity and budget constraints. The solution is 8 adults and 32 children.

Explanation:

We are given a situation where a company charges $18 for each adult (a) and $8 for each child (c) for a bus trip to an upcoming play, with the constraints that the bus holds a maximum of 40 people and the available budget is $400. To find the maximum number of adults and children that can attend under these constraints, we need to set up a system of equations:

For the capacity constraint: a + c = 40

For the budget constraint: 18a + 8c = 400

We can solve this system using substitution or elimination. Let's use elimination. Multiply the first equation by -8 and add it to the second equation to eliminate c:

-8a - 8c = -320

18a + 8c = 400

Adding these two equations together gives us:

10a = 80

Thus, a = 8. Plugging a = 8 back into the first equation, we get c = 32.

The maximum number of adults and children that can attend the play is 8 adults and 32 children.

Final answer:

In the equation f(-11)=5x+1, solving for x yields x = -2.4.

Explanation:

To find what x equals in the function f(-11)=5x+1, we start by understanding that the function f(x) identifies the relation between x and f(x). In this case, f(-11) has been given the value of 5x+1. Therefore, we solve for x by setting the expression equal to f(-11).

We have the equation 5x + 1 = f(-11). Since f(-11) is given as a constant, we substitute and solve for x:

5x = -12

x = -2.4

Hence, x equals -2.4 in the function f(-11)=5x+1.

Step-by-step explanation:

thirty percent of $28 is $8.4, so you would subtract the two leaving you with $19.6

2.5 sales tax of $19.6 is $0.49

Adding those two, the total comes to 20.09 which is just over budget

The amount of the book is more than $20. Then she does not have enough money.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Let 'x' be the markdown price. Then the equation is given as,

30% = [(28 - x) / 28] × 100

0.30 = [(28 - x) / 28]

8.4 = 28 - x

x = $19.6

Then the amount of book after tax is given as,

⇒ $19.6 x 1.025

Answer:

The annual interest rate is 5.247%.

Step-by-step explanation:

Question

Claire deposited $2,500 into an account that accrues interest monthly. She made no additional deposits or withdrawals. After 2 years, Claire had $2,762.35 in the account. what is the annual interest rate of the account?

Subtract $2,500.00 from $2,762.35 and you get 262.35- the 2-year interest. To get the annual interest, divide 262.35 by 2, which equals 131.75. Then, divide 131.75 by 2,500 (original amount) and you get 0.05247. Lastly, multiply 0.05247 by 100 to get the answer (5.247%).

To find the annual interest rate, use the compound interest formula and set it equal to the final amount in the account. After performing the necessary computations, 'r' comes out to approximately 5%.

To find the annual interest rate of Claire's account, you'll need to use the compound interest formula: v(t) = p * (1 + r/n)^(nt), where:

Claire's account had $2,762.35 in it after 2 years. Therefore, you would set $2,762.35 equal to the formula and solve for 'r'.

Doing so yields $2,762.35 = $2,500 * (1 + r/12)^(12*2) which simplifies, after some mathematical computations, to an annual interest rate (r) of roughly 5%.

Answer:

a. Number of people surveyed were 900.

b. 360 people preferred running.

Step-by-step explanation:

Given:

On a recent survey, 60% of those surveyed indicated that they preferred walking to running.

If 540 people preferred walking.

Now, to find a. number of people were surveyed. b. number of people preferred running.

a.

Number of people preferred walking = 540.

Percentage of people preferred walking = 60%.

Let the total number of people surveyed be [tex]x.[/tex]

Now, to get the number of people surveyed:

60% of x = 540.

[tex]\frac{60}{100} \times x=540[/tex]

[tex]0.60\times x=540[/tex]

[tex]0.60x=540[/tex]

Dividing both sides by 0.60 we get:

[tex]x=900.[/tex]

Thus, number of people surveyed = 900.

b.

Total number of people surveyed = 900.

People preferred walking = 540.

Now, to get the people preferred running we subtract people preferred walking from total number of people surveyed:

[tex]900-540[/tex]

[tex]=360.[/tex]

Thus, people preferred running = 360.

Therefore, a. Number of people surveyed were 900.

b. 360 people preferred running.

[tex]\displaystyle \frac{5}{s}\times \frac{2}{5} =\frac{2}{s}[/tex]

Step-by-step explanation:

Errors in Algebraic Operations

It's usual that students make mistakes when misunderstanding the application of algebra's basic rules. Here we have two of them

The first expression is

[tex]1-x / (5-x)(-x)=x-1 / x(x-5)[/tex]

Let's arrange into format:

[tex]\displaystyle \frac{1-x}{(5-x)(-x)} =\frac{x-1 }{ x(x-5)}[/tex]

We can clearly see in all of the factors in the expression the signs were changed correctly, but the result should have been preceeded with a negative sign, because it makes 3 (odd number) negatives, resulting in a negative expression. The correct form is

[tex]\displaystyle \frac{1-x}{(5-x)(-x)} =-\frac{x-1 }{ x(x-5)}[/tex]

Now for the second expression

[tex]5/s+2/5=2/s[/tex]

Let's arrange into format

[tex]\displaystyle \frac{5}{s}+\frac{2}{5} =\frac{2}{s}[/tex]

It's a clear mistake because it was asssumed a product of fractions instead of a SUM of fractions. If the result was correct, then the expression should have been

[tex]\displaystyle \frac{5}{s}\times \frac{2}{5} =\frac{2}{s}[/tex]
