4/5 = x/30, then (4×30)/5 =24

The missing value is 24.

We have,

From the figure,

We can write an expression as:

4:5 = x : 30

This can be written as,

4/5 = x/30

Now,

Cross multiply.

x = 4 x 30 / 5

x = 4 x 6

x = 24

Thus,

The missing value is 24.

Explain how to solve 5x^2-3x=25 by completing the square. What are the solutions?

Answers

Answer:

x1 = √(509) /100 + 3/10

x2  = -√(509) /100 + 3/10

Step-by-step explanation:

We do completing the square as follows:

1. Put all terms with variable on one side and the constants on the other side.

5x^2 - 3x = 25

2. Factor out the coefficient of the x^2 term.

5(x^2 - 3x/5) = 25

3. Inside the parentheses, we add a number that would complete the square and also add this to the other side of the equation. In this case we add 9/100 and on the other  side we add 9/20.

5(x^2 - 3x/5 + 9/100) = 25 + 9/20

4. We simplify as follows:

5(x^2 - 3x/5 + 9/100) = 25 + 9/20

5(x - 3/10)^2 = 509/20

(x - 3/10)^2 = 509/100

x1 = √(509) /100 + 3/10

x2  = -√(509) /100 + 3/10

Given a and b are numbers, and a + b = 180, which
statements also must be true?
a = 180 - 6
a - 180 = b
360 = 2a + 2b
a = 90 and b = 90

Answers

If the first one is a = 180 - b, and not 180 - 6, then that is correct.

Also, 360 = 2a + 2b is correct

Answers

Answer:

120 minutes

Step-by-step explanation:

12 x 10 = 120

10 x 12 = 120

15 x 8 = 120

You will put the muffins in 10 times and you will put the cookies in 12 times then you will put the scones in 8 times. If you have different numbers, you can first start out with one number and times all of the numbers by that one number. For example I picked 5 to start out with:

12 x 5 = 60 minutes 10 x 5 = 50 minutes 15 x 5 = 75 minutes.

Then I did 12 x 6 = 72 minutes, 10 x 6 = 60 minutes, 15 x 6 = 90 minutes

Since I still don't have the numbers to add up to the same answer, I went to timing them by 7:

12 x 7 = 84 minutes, 10 x 7 = 70 minutes, 15 x 7 = 105 minutes

They are still not the same answer so lets try 8:

12 x 8 = 96 minutes, 10 x 8 = 80 minutes, 15 x 8 = 120 minutes.

Since I don't want to go farther than 120 minutes, I will keep trying different numbers for the other ones besides 15.

12 x 9 = 108 minutes, 10 x 9 = 90 minutes

12 x 10 = 120 minutes, 10 x 10 = 100 minutes

Now we will focus on getting 10 to 120 because we got 12 to 120.

10 x 11 = 110 minutes

10 x 12 = 120 minutes

To sum all of this, it took 8 trips to get 15 minutes to 120 minutes, 10 trips to get 12 minutes to 120 minutes, and 12 trips to get 10 minutes to 120 minutes.

One more way to think about this is:

10, 12, and 15 can go into 120 evenly.

[tex]12\sqrt{120} = 10[/tex]

[tex]10\sqrt{120} = 12\\15\sqrt{120} = 8[/tex]

The exponential function from the table is given by y = 2(2)ˣ

What is an exponential function?

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

At x = 0, y = 2, hence a = 2

At x = 1, y = 4, hence:

4 = 2b¹

b = 2

Solve 4ax + 5ax = 6 ax + 9 for x. Assume a = 0.

Answers

Step-by-step explanation:

4ax + 5ax = 6 ax + 9

If a=0

Then

0+0≠0+9

so x is undefined

If the value of 'a' is zero. Then the solution of the equation will be not defined.

What is the solution to the equation?

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

The equation is given below.

4ax + 5ax = 6ax + 9

Simplify the equation for x, then the equation is given as,

4ax + 5ax = 6ax + 9

4ax + 5ax - 6ax = 9

3ax = 9

x = 3 / a

If the value of 'a' is zero. Then the solution of the equation will be

x = 3 / 0

x = not defined

If the value of 'a' is zero. Then the solution of the equation will be not defined.
