Answer: X = 0

25 x ^ 2 - 10 x = 0

25 * 0 ^ 2 - 10 * 0 = 0

25 * 0 - 10 * 0 = 0

0 - 0 = 0

0 = 0

and

25 x ^ 2 - 10 x = 0 Divide both sides by 5 x

25 x ^ 2 / 5 x - 10 x / 5 x = 0 / 5 x

5 * 5 * x * x / 5 x - 2 * 5 x / 5 x = 0

5 x - 2 = 0 Add 2 to both sides

5 x - 2 + 2 = 0 + 2

5 x = 2 Divide both sides by 5

5 x / 5 = 2 / 5

x = 2 / 5

x = 0 and x = 2 / 5

25 x ^ 2 - 10 x = 0

25 * 0 ^ 2 - 10 * 0 = 0

25 * 0 - 10 * 0 = 0

0 - 0 = 0

0 = 0

and

25 x ^ 2 - 10 x = 0 Divide both sides by 5 x

25 x ^ 2 / 5 x - 10 x / 5 x = 0 / 5 x

5 * 5 * x * x / 5 x - 2 * 5 x / 5 x = 0

5 x - 2 = 0 Add 2 to both sides

5 x - 2 + 2 = 0 + 2

5 x = 2 Divide both sides by 5

5 x / 5 = 2 / 5

x = 2 / 5

x = 0 and x = 2 / 5

It would be equalto 2.4 * 10^6

HIGH SCHOOL

The ensemble is selling tickets to a performance. An adult ticket costs $9 and a child's ticket costs $4. The students would like ticket sales of at least $1300, and the auditorium can hold no more than 200 audience members. Let x = The number of adult tickets, and let y = The number of child tickets.

Answer:

Step-by-step explanation:

Let x represent the number of adult tickets that were sold.

Let y represent the number of children tickets that were sold.

The auditorium can hold no more than 200 audience members. This means that

x + y ≤ 200

An adult ticket costs $9 and a child's ticket costs $4. The students would like ticket sales of at least $1300. This means that

9x + 4y ≥ 1300

These are the set of inequalities that represents the situation.

COLLEGE

The Jurassic Zoo charges $14 for each adult admission and $9 for each child. The total bill for the 214 people from a school trip was $2081. How many adults and how many children went to the zoo?

a=adult

c=child

a+c=214

c=214-a

9c+14a=2081

9(214-a)+14a=2081

1926-9a+14a=2081

5a=155

a=155/5=31

31 adults

183 children

check

31*14 = 434

183*9=1647

1647+434=2081

24 POINTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Mr. Yu applies 1/2 ounce of fertilizer to every 5/8 square meter of his lawn.

How many ounces of fertilizer does Mr. Yu use per square meter for his lawn?

1/2 : 5/8

If you divide both sides by 5/8 the left side will become 1 giving you the answer:

1/2) / (5/8

1/2*8/5

8/10

4/5

4/5:1

The solution to the system of equations shown is (2,0). 3x – 2y = 6

x + 4y = 2

When the first equation is multiplied by 2, the sum of the two

equations is equivalent to 7x = 14

Which system of equations will also have a solution of (2,0)?

The system of equation will also have a solution of (2,0) are,

x + 4y = 2, 7x = 14.

Given that,

The solution to the system of equations shown is (2,0).

3x – 2y = 6 , x + 4y = 2

When the first equation is multiplied by 2, the sum of the two equations is equivalent to 7x = 14.

We have to determine,

Which system of equations will also have a solution of (2,0).

According to the question,

To determine the system of the equation after applying all the given conditions in the steps, follow all the steps given below.

System of equations; 3x – 2y = 6 , x + 4y = 2.

- Step1; Multiply the first equation by 2,

- Step2; Adding equation 1 after multiplying by 2 from equation 2.

- Step3; When x = 2 the value of y is,

Hence, The required system of equation will also have a solution of (2,0) are, x + 4y = 2, 7x = 14.

Solve the following equation below ax=15+b

Solve for x.

Here is your equation:

You're trying to find x alone. To find a specific variable, you have to do the opposite of what's happening to the variable, which is x in this equation.

In this equation, x is being multiplied by a. That means you have to do the opposite of multiplying, which is dividing by a. To leave x alone, divide both sides by a.

Now that you have divided both sides by a, which leaves x alone, you have:

Your answer is

If you have any questions, feel free to ask in the comments! :)

Answer:

x=15/a+b/a

Step-by-step explanation:

a*x=15+b

you need to move all the variables (a) to one side and to do that you can re-organize it to say

x*a=15+b

to get the answer you need to divide (a) and that gets you your answer,

x=15/a+b/a

Calculate S30 for the arithmetic sequence defined by {an}={3.1n-2} a.) 91

b.) 113

c.) 1,381.5

d.) 1,397.5

Answer:

c) 1,381.5.

Step-by-step explanation:

First term = 3.1 *1 - 2 = 1.1

2nd term = 3.1*2 - 2 = 4.2

3rd term = 3.1*3 - 2 = 7.3

so the common difference d = 3.1.

S30 = (30/2) [ 2* 1.1 + (30-1) * 3.1)]

= 1,381.5.
