I need Help! ASAP: The current temperature in Lansdowne is 20°F. This is 6 degrees less than twice the temperature that it was five hours ago. Write and solve an equation to determine the temperature in Lansdowne five hours ago.

Answers

Answer 1

Answer:

13*f

Step-by-step explanation:

20*f + 6*f ÷ 2 = 13*f

hope it helps please like

Answer 2

Answers: 2x - 6 = 20 & x = 13

Explanation: The x in this equation is the temperature 5 hours ago. In the word problem, 20 degrees is the x temperature multiplied by 2 (since it says “twice the temperature”) and subtracted by 6 (since it says “6 degrees less). Therefore, the equation would be the x changing (due to the multiplying of 2 and subtraction of 6) that equal 20. When solving, first check to see if there are any like terms (None in this problem). Next, isolate the variable. Here, you add the opposite of 6 to both sides (-6 + 6 and 20 + 20). This makes it 2x = 26. Now divide by the coefficient (2x / 2 and 26 / 2). This will be x = 13. Hope this helped!

True or false, the two expressions are equivalent.

3(4a - 2) and 12a - 6

Answers

Answer:

its true because 3(4a - 2) is 12a - 6

Answer:

True

Step-by-step explanation:

its true because 3(4a - 2) you would do 3 x 4a and instead of 4 - 2 you would change it to 4 + 2 after that you would do 3 x 4a = 4a + 2 which gives you

12a - 6

so yes they are equivalent

Answer:

D.

Step-by-step explanation:

Form an equation. 593 = 418 + 12.50d

The variable d represents how many days she needs to pet-sit for.

Use the subtraction property of equality by removing 418 from both sides.

593 - 418 = 418 - 418 + 12.50d

175 = 12.50d

You will need to divide both sides by 12.50 to get the variable by itself.

14 = d

Write an expressions for the missing dimension of each shaded figure and a multiplication expression for it's area

Answers

Answer:

alrighty then, x has to be 14, so x-3=11 which means the question mark would be 3. you can do the rest yourself, I believe in you!

Step-by-step explanation:

To solve this problem, we are required to write and expression to solve for the missing side in each figure.

Side of a Square

To find the missing side of the square, we can simply write it as

[tex]15 = h + x\\x = (15 - h)m[/tex]

For the triangle, to find the missing side let's calculate the area of the triangle

[tex]area = \frac{1}{2} base * height\\area = \frac{1}{2} * 5 * 12\\area = 30m^2[/tex]

But for the length of the missing side, we can simply write it as

[tex]b = 10 + x\\x = (b - 10)m[/tex]

The expressions for the missing sides are;

x = (15- h)mx = (b - 10)m

A dilation with a scale factor of 1/3 is a reduction. A dilation with a scale factor of 2 is a reduction . which is true and which is false

Answers

Answer:

True: A dilation with a scale factor of 1/3 is a reduction.

False: A dilation with a scale factor of 2 is a reduction.

Step-by-step explanation:

A dilation with a scale factor between 0 and 1 is a reduction because the image will decrease in size.

On the other hand, a dilation with a scale factor greater than 1 is an enlargement, where the image increases in size.

So, the statement that a dilation with a 1/3 scale factor is a reduction is true.

The other statement is false, which says a dilation with a scale factor of 2 is a reduction.

Answer: The speed of the car is 45.3 miles per hour.

Step-by-Step Explanation: Let 'x' be the speed of the car.

60 × 2/3 = 120/3 = 40

30 × 1/5 = 151/5

151/5 /40 = x / 60

151 / 200 = x / 60

=> x = (151×60) / 200

=> x = 45.3

Answer:

The car was traveling at an average speed of 45.3 miles per hour.

Step-by-step explanation:

We need to figure out how many minutes are in 2/3 of a hour. If we divide 60 minutes by 3 we get 20 minutes, so 2/3 of 60 minutes is (20 minutes x 2) 40 minutes.

We now know that the car traveled 30.2 miles in 40 minutes. We want to know if it traveled for 60 minutes, what would the average speed be. The ratio will be the same, so we want to solve for x (miles):

30.2/40=x/60

We then cross multiply:

30.2x60=40(x)

1,812=40(x)

Divide each side by 40

1,812/40 = x

x=45.3

Answers

Answer:

x = 40°

Step-by-step explanation:

Straight angle is equal to 180°

Angle x, 60° and 80° form a straight angle.

Then we have following equation to solve for x:

x + 60° + 80° = 180°x + 140° = 180°x = 180° - 140°x = 40°
X = 40 degrees
