find the value of x..

Answer:

x>3

Step-by-step explanation:

4 • (7 - x) -  16  < 0

3.1     Pull out like factors :

12 - 4x  =   -4 • (x - 3)

-4 • (x - 3)  < 0

4.1    Divide both sides by  -4

4.2      Add  3  to both sides

            x > 3

4.3      Inequality plot for

        -4.000 X  + 12.000  >  0

Answer:

1/x = 1/4 + 1/3

Step-by-step explanation:

In 4 hours Bethany did the whole fraction 1 of the house.

In 1 hour he would do 1/4 of it.

In 3 hours Colin did the whole fraction 1 of the house.

In 1 hour he would do 1/3 of it.

In 1 hour they would both do (1/4 + 1/3)

If it takes both of them x hours to finish 1 whole fraction of the house.

In 1 hour they will both do 1/x

That means that:

1/x = 1/4 + 1/3

That is the equation. x can be solved for.

Answer:

x - 16.1°C

Step-by-step explanation:

Given that average low temperature in January is 16.1 cooler Than average low temperature in November

Let average low temperature in November = x

Since, average low temperature in January is cooler than average low temperature in November, then, January temperature is less Than in November

Hence,

Average low temperature in January :

[Average low temperature in November - 16.1°C]

(x - 16.1°C)

Answer:

no

Step-by-step explanation:

5(x - 1) = 5x - 5

5x - 1 = 5x - 1

No, it is not equivalent

The required, 5(x - 1) and 5x - 1 are not equivalent expressions.

Let's expand 5(x - 1):

5(x - 1) = 5 * x + 5 * (-1) = 5x - 5

On the other hand, 5x - 1 is already in its simplified form.

As you can see, the expressions 5(x - 1) and 5x - 1 have different forms. The first expression involves distributing the 5 to both terms inside the parentheses, while the second expression is already simplified and cannot be further combined.

For example, if we substitute x = 2 into both expressions, we get:

5(2 - 1) = 5 * 1 = 5

5 * 2 - 1 = 10 - 1 = 9

Since 5 and 9 are not equal, it confirms that the two expressions are not equivalent.

Answer:

15%

Step-by-step explanation:

Given that:

Number of people who went to swimming pool in the first week = 1120

In second week, there are 100 fewer people, so

Number of people who went to swimming pool in the second week = 1020

In third week, there are 140 more people, so

Number of people who went to swimming pool in the third week = 1160

In fourth week, there are 208 fewer people, so

Number of people who went to swimming pool in the fourth week = 952

To find:

Percentage decrease in the number of people who went to the pool over the four weeks?

Solution:

Initial value = 1120

Final value = 952

Decrease in the value = Final value - Initial value

Decrease in the value = 1120 - 952 = 168

To find the percentage, we need to take the initial value in the consideration.

Therefore, percentage decrease is:

[tex]\dfrac{Decrease}{Initial\ value}\times 100[/tex]

[tex]\Rightarrow \dfrac{168}{1120}\times 100\\\Rightarrow \bold{15\%}[/tex]

Answer:

Step-by-step explanation:

Answer:

20 percent

Step-by-step explanation:

Just divide 100 by 65 and multiply that number by 13.

Answer:

20%

Step-by-step explanation:

This is the answer because:

1) Convert the fraction to a decimal, then multiply by 100:

13 x 100 ÷ 65 = 20

Therefore, the answer is 20%

Answer: 4.82 km

Step-by-step explanation:

You went for a run on Monday.

You then went on a run on Tuesday as well. On this day you ran 2.41 km and it is said that you ran the same distance on both days which means you ran for 2.41 km on Monday as well.

The total distance you ran is therefore:

= 2.41 + 2.41

= 4.82 km

Answer:

18 + 6m > 80

Step-by-step explanation:

We are told that:

Addison wants to ride her bicycle more than 80 miles this week.

The inequality representing this sign is given as > (greater than).

Let the number of miles be represented as= m

Hence:

She has already ridden her Bicycle 18 miles.

The algebraic inequality use to determine the average number of miles m she would need to ride her bicycle each day for six more days to achieve her goal is given as:

18 + 6 ×m > 80

18 + 6m > 80

The correct function which represents the situation is,

⇒ f (x) = 2 (x + 1)² + 2

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The minimum of the graph of a quadratic function is located at (-1, 2). The point (2, 20) is also on the parabola.

Now, By options;

The correct function has a point (2, 20).

Hence, It can satisfy the equation of parabola.

Now, By option 3;

⇒ f (x) = 2 (x + 1)² + 2

⇒ 20 = 2 (2 + 1)² + 2

⇒ 20 = 2 (9) + 2

⇒ 20 = 18 + 2

⇒ 20 = 20

Hence, The correct function which represents the situation is,

⇒ f (x) = 2 (x + 1)² + 2

The manager of the zoo where the ticket price for an adult is $9.50 and the ticket price for a child is $6.50 wants to make at least $800 on a Saturday. Let x be the number of adult tickets and y be the number of child tickets. Choose the inequality that shows the numbers of tickets that need

A) 9.50x + 6.50y ≥ 800

B) 9.50x + 6.50y < 800

C) 9.50x + 6.50y > 800

D) 9.50x + 6.50y ≤ 800

Answer:

A) 9.50x + 6.50y ≥ 800

Step-by-step explanation:

Let x be the number of adult tickets and y be the number of child tickets

We are told that the zoo wants to make at least $800, this means greater than or equal to $800

Therefore, inequality equation is given as:

$9.50 × x + $6.50 × y ≥ 800

= 9.50x + 6.50y ≥ 800

Therefore option A) 9.50x + 6.50y ≥ 800 is correct.
