Answer:

x = 1/a

Step-by-step explanation:

To solve 7ax + 8ax = 9ax + 6 for x, we can start by combining like terms on both sides of the equation:

7ax + 8ax = 9ax + 6

becomes

15ax = 9ax + 6

Next, we can subtract 9ax from both sides of the equation:

15ax - 9ax = 9ax + 6 - 9ax

becomes

6ax = 6

Finally, we can divide both sides of the equation by 6a to find the value of x:

6ax / 6a = 6 / 6a

becomes

x = 1/a

So, the solution for x is x = 1/a.

ms. avila got blue ribbons to give to participants at the school science fair. she ordered 120 blue ribbons from the smart start school supplier. since this was a bulk order, smart start reduced the price of each blue ribbon by $0.75. the total came to $60. which equation can you use to find the amount of money, b, smart start normally charges for a blue ribbon?

Answers

The equation 120(b - 0.75) = 60 can you use to find the amount of money, b, smart start normally charges for a blue ribbon

Ms. Avila ordered 120 blue ribbons from the smart start school supplier.

Smart start reduced the price of each blue ribbon by $0.75.

The total came to $60.

To express the problem in equation we have to read the question carefully and write the equation according to question.

Let the price of 1 blue ribbon = b

If he reduce the price by 0.75, then the price of blue ribbon = (b - 0.75)

She buy total blue ribbons = 120

So the price of 120 blue ribbons = 120(b - 0.75)

But the total cost is $60.

So the equation is:

120(b - 0.75) = 60

A man has twelve identical marbles in his pockets consisting of five green, two white, three blue and two red. He draws out a marble at random a) what is the probability that it is either green or a blue marble? b) if the man makes two draws one of after the order from his pocket without replacement, what is the probability that; i) The first draw will be a green and the second draw, a blue marble? ii) neither is a red marble?

Answers

Answer:

Green: 5; White: 2; Blue: 3; Red: 2; Total: 12

A) 8/12

i) 5/12 and 3/11

ii) 10/12

Hope this helps!

Step-by-step explanation:

a) The probability that it is either green or a blue marble is 2/3

b) The probability that first draw will be a green and the second draw, a blue marble is 3/44

c) The probability that neither is a red marble is 15/22

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

A man has twelve identical marbles in his pockets consisting of five green, two white, three blue and two red

Now , the probability is

a)

The probability that it is either green or a blue marble is P(green or blue) = P(green) + P(blue)

P(green) + P(blue) = 5/12 + 3/12

P(green) + P(blue) = 8/12 = 2/3

Therefore , the probability is 2/3

b)

The probability that first draw will be a green and the second draw, a blue marble is P(green and blue) = P(green) x P(blue | green)

P(green) x P(blue | green) = (5/12) x (3/11)

P(green) x P(blue | green) = 15/132

c)

The probability that neither is a red marble is P(neither draw is red) = P(non-red on first draw) x P(non-red on second draw | non-red on first draw)

P ( neither red ) = ( 5/6 ) ( 9/11 )

P ( neither red ) = 15/22

Hence , the probability is solved

Factoring out 3x^2+2x-21=0

Answers

The factors of the equation 3x^2+2x-21=0 are (3x - 7) (x + 3) = 0 and x = -3 and x = 7/3.

How to solve quadratic equations?

All related terms should be combined and moved to one side of the equation. Moving all of the components to one side of an equation while maintaining the x2 term positive is the first step in factoring an equation. The x2 terms, x terms, and constants (integer terms) must all be added to or subtracted from one another, and they must all be moved to one side of the equation so that nothing is left on the other. You may just write "0" on the other side of the equal sign if that side has no more words.

Given that the equation is 3x^2 + 2x -21 = 0

Using the method of expansion to solve the quadratic equation we have:

3x^2 + 2x -21 = 0

Multiply (a)(c) and find its prime factors:

(3)(21) = 63

Prime factors: 7, 9

Using the factors deduce the middle term:

3x^2 + 9x - 7x -21 = 0

Take the common in the first two and the last two terms:

3x(x + 3) -7(x+3) = 0

(3x - 7) (x + 3) = 0

Equate to 0:

(x + 3) = 0

x = -3

(3x - 7) = 0

x= 7/3

Hence, the factors of the equation 3x^2+2x-21=0 are (3x - 7) (x + 3) = 0 and x = -3 and x = 7/3.

Find the value of x in the rhombus.
(2x^2-25x)
(3x^2+60)

Answers

The value of x in the rhombus is -1

How to determine the value of x

From the question, we have the following parameters that can be used in our computation:

The shape = rhombus

The diagonals of rhombus bisect each other at 90 degrees

So, we have

2x^2 - 25x + 3x^2 + 60 = 90

Evaluate the like terms

5x^2 - 25x - 30 = 0

Divide through by 5

x^2 - 5x - 6 = 0

So, we have

x^2 + x - 6x - 6 = 0

Factorize

(x + 1)(x - 6) = 0

This gives

x = -1 and x = 6

When x = 6, 2x^2 - 25x is negative

Hence, the value of x is -1

Answers

If a paper company needs to ship paper to a late printing business. 12 small boxes were shipped and 8 large boxes were shipped.

How to find the number of boxes shipped?

Using a system of equations to represent the problem.

Let x represent the number of small boxes shipped

Let  y represent the number of large boxes shipped.

We know that:

x + y = 20 (the total number of boxes shipped)

8x + 21y = 264 (the combined volume of all boxes )

Solving the first equation for y: y = 20 - x

Substituting this expression for y into the second equation:

8x + 21(20 - x) = 264

8x + 420 - 21x = 264

-13x = -156

x = 12 (small boxes)

Answers

The rate of change of the radius when the radius is 2 is approximately 4 / (π³ * 2⁵).

Rate of Change of Radius

The volume of a hyper-ball is given by:

         V = (1/6) * π³ * r⁶

Taking the derivative with respect to time, we get:

         dV/dt = (1/6) * π³ * 6 * r⁵ * dr/dt

We are given that the rate of change of the volume is 4 per second, so we can write:

          dV/dt = 4

Substituting the given value of r = 2:

       4 = (1/6) * π³ * 6 * 2⁵ * dr/dt

Solving for dr/dt:

       dr/dt = 4 / ((1/6) * π³ * 6 * 2⁵) = 4 / (π³ * 2⁵)

So the rate of change of the radius when the radius is 2 is approximately  with this one: dr/dt = 4 / (π³ * 2⁵).
