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!

Find the length of the radius of the following circle. x² + y² = 16 4 8 16
Morgarella [4.7K]
Please, when you present a list of numbers, such as 4, 8, 16, ..., separate them with commas or semicolons:  4, 8, 16, ...

If x^2 + y^2 = 16, then 16 represents r^2, and r = 4.  r cannot be negative in this type of problem.

The length of a rectangle is 12 in and the perimeter is 56 what us the width of the rectangle
Aleks [24]
Hi there!

We can find the perimeter of a rectangle by using the following formula:

perimeter = 2 × width + 2 × length

In the question, we are given the following data: the length of the rectangle is 12 in and the perimeter is 56. Let's substitute this into our formula!

56 = 2 × width + 2 × 12
Multiply first.

56 = 2 × width + 24
Now subtract 24 from both sides.

32 = 2 × width
And finally, to find the width of the rectangle, divide both sides of the equation by 2.

16 = width
(we can eventually switch sides in the equation).

width = 16
~ Hope this helps you!
