Mathematics Middle School

please help for brainliest imbegging you this is confsiusing to me


The work of a student to solve the equation 4(2x − 4) = 8 + 2x + 8 is shown below:


Step 1: 4(2x − 4) = 8 + 2x + 8

Step 2: 6x − 8 = 16 + 2x

Step 3: 6x − 2x = 16 + 8

Step 4: 4x = 24

Step 5: x = 6



In which step did the student first make an error and what is the correct step?


Step 2; 8x − 4 = 2(6 + x + 6)

Step 2; 8x − 16 = 16 + 2x

Step 3; 6x − 2x = 16 − 8

Step 3; 6x + 2x = 16 + 8

Answers

Answer 1
Step 2; 8x-16 = 16+2x
Answer 2
It would be step 2 :)))

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:

13*f

Step-by-step explanation:

20*f + 6*f ÷ 2 = 13*f

hope it helps please like


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!

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.
