if the sum of a number and nine is doubled, the result is seven less than the number. find the number.

1 answer:

3 0

X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7

We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25

answer: the number would be: -25.

We can measure temperature in two different common units degrees Celsius in degrees Fahrenheit the variable X represents the tem

labwork [276]

Answer: 50° Fahrenheit

Step-by-step explanation:

Here, the equation that shows the temperature of x degree Celsius in Fahrenheit is,

$F(x) = 32^{\circ} + 1.8\times x$

Where x is a variable.

Thus, For the temperature of 10° Celsius,

x = 10° Celsius

The temperature in Fahrenheit is,

$F(10^{\circ}C) = 32^{\circ} + 1.8\times 10$

$= 32^{\circ} + 18^{\circ}$

$=50^{\circ}\text{ Fahrenheit}$

Thus, the increasing temperature by 10° C is equivalent to increasing temperature by 50° F.

Two distinct number cubes, one red and one blue, are rolled together. Each number cube has sides numbered 1 through 6.

algol [13]

Answer:

7/18

Step-by-step explanation:

First we need to find what values of sum we can have.

The minimum value for a cube is 1, so the minimum value for the sum is 2.

The maximum value for a cube is 6, so the maximum value for the sum is 12.

Now, we find the multiples of 6 and the multiples of 4 between 2 and 12:

4, 6, 8, 12.

To have a sum of 4, we can have the pairs:

(1,3), (2,2), (3,1)

To have a sum of 6, we can have the pairs:

(1,5), (2,4), (3,3), (4,2), (5,1)

To have a sum of 8, we can have the pairs:

(2,6), (3,5), (4,4), (5,3), (6,2)

To have a sum of 12, we can have the pairs:

(6,6)

So we have 14 pairs among the 36 (6 possibilities of each cube, so 6*6=36) total possibilities of pairs, so the probability is P = 14/36 = 7/18

The average professional hockey player makes $2.78 million a year.

Nimfa-mama [501]

The average hockey player makes per game is an amount of $34,000.00 which is the correct option would be option (A).

<h3>What is the division operation?</h3>

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.

For example 4/2 = 2

The average professional hockey player makes $2.78 million a year.

$2.78 million = $2,780,000

They play an average of 82 games.

The average hockey player makes per game = 2,780,000 / 82

Apply the division operation to get the answer.

The average hockey player makes per game = 33,902.439

The average hockey player makes per game = $33,900.00

Type the equation for the graphbelow.Pi/3 2piy = [?] sin([ ]x)

Pie

To find the equation of the graph, what we do is to recognize some characteristics of a sine function:

- Amplitude: The amplitude of the sine function is the distance from the middle value or line running through the graph up to the highest point. In this case, the amplitude is 1.

- Period: The period of a sine function is defined as the length of one complete sine wave or one complete cycle of the curve. It can be found using the equation: P=2pi/B.

Why are these characteristics important?

Because the sine function has the following general form:

In this problem, we have A=1 and we know that the period equals 2pi/3. So,

Therefore, the equation of the graph is:
