Bethany can mow her lamily's lawn in 4 hours. Her brother coin can mow the lawn into hoursWhich equation can ve
used to find the number of hours, x, it would take for Bethany and Colin to mow the lawn together?

Answers

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.

1.) Multiply both sides of the equation by 3:[tex]\frac{t}{3}[/tex] × [tex]3=t[/tex][tex]-11[/tex] × [tex]-3=-33[/tex]

 - We do this because we need to get x alone and separate from fraction from.

2.) Add 33 to both sides:[tex]-33+33=[/tex] Cancels Out[tex]-6+33=27[/tex]

5(x - 1) and 5x - 1
is it equivalent ​

Answers

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.

Addison wants to ride her bicycle more than 80 miles this week. She has already ridden her Bicycle 18 miles. Write an 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?

Answers

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

What is the center of the circle x² + y2 - 4 = 0?

Answers

Answer:

(0,0)

Desmos graphing calculator is a great way to enter the formula of a circle and see a visual example.

Answer: (0,0)

Explanation: The equation for a circle is (x - h)^2 + (y - k)^2 = r^2, where (h,k) is the vertex and r is the radius. Rearranging the given equation, we have that x^2 + y^2 = 4. Therefore, the center of the circle is (0,0), and its radius is 2.

Otto is told the average low temperature in January is 16.1∘C cooler than the average low temperature in November. What equation can Otto use to find the average low temperature in January?

Answers

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)

In the first week of​ July, a record 1,120 people went to the local swimming pool.In the second week, 100fewer people went to the pool than in the first week. In the third​ week,140 more people went to the pool than in the second week. In the fourth week, 208 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four​ weeks?

Answers

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]

The correct function which represents the situation is,

⇒ f (x) = 2 (x + 1)² + 2

What is an expression?

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
