Assuming the side of the rectangle are (L) length and (W) width, the perimeter:
2L + 2W = 234
:
"the rectangle is twice as long as it is wide,", the equation for this statement:
L = 2W
:
In the first equation, we can replace L with 2W, then we have
2(2W) + 2W = 234
4W + 2W = 234
6W = 234
Divide both sides by 6
W = 234%2F6
W = 39 meters is the width
:
Remember it said the length is twice the width, therefore:
L = 2(39)
L = 78 meters is the length
:
:
Check this by finding the perimeter with these values
2(78) + 2(39) =
156 + 78 = 234

-|16.25| +20
How do I solve this?
Hey!! Glad I can help!!!
Answer:
-16.25+20=3.75
Step-by-step explanation:
the negative sign is outside the box so it does not affect the absolute value.
then do -16.25+20 and you get 3.75.
If satisfied leave a review and feel free to give brainiest.
Answer: 1. You have to solve -|16.25| first, which the answer is -16.25. 2. Now you add 20. -16.25+20=3.75

Write 3 and 3/4 as a decimal. Is it repeating or terminating?
Answer:
3.75, Terminating
Step-by-step explanation:
To answer this, we simply have to find what 3/4 is as a decimal. So, we know that in order to make 4/4, or 1, we need 4 parts. Let's say that 4/4 would equal 100, so we need to divide 100 into 4 parts:
100 / 4 = 25
Now, to find what 3/4 is, all we have to do is multiply 25 by 3:
25 * 3 = 75
And that is our decimal form, we just need to add the 3:
3.75, and since .75 doesn't keep on repeating, it just stops at .75, this is a terminating decimal
Hope this helps! :)

Step-by-step explanation:
I got the same thing as the other person, but typing it out would take forever just to give you the same result.
You do use a technique called rationalizing a denominator to eliminate the radical. The point of rationalizing a denominator is to make it easier to understand what the quantity really is by removing radicals from the denominators.
1) ( 6+[tex]\sqrt{6}[/tex] ) / 2

Answer:
the temperature at noon was 22 can i get brainliest please? :)
Step-by-step explanation:
-5 + 27 = 22
The temperature at noon after a rise of 27°C will be 22°C.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem accurately and completely.
At sunrise, the temperature outside was 5°C below zero By noon the temperature rose to 27°C. Then the temperature at noon is given as,
⇒ 27°C + (-5°C)
⇒ 27°C - 5°C
⇒ 22° C
The temperature at noon after a rise of 27°C will be 22°C.

Step 2: 20x = 80 + 10x
Step 3: 10x = 80
Step 4: x= 8
Answer:
Step 2: 20x = 80 + 10x
Step-by-step explanation:
Step 1: 20x - 10 = 80 + 10x
Add 10 to each side
20x - 10+10 = 80+10 + 10x
20x = 90 + 10x

An object is moving at a speed of 6 feet per day. Express this speed in miles per year. Round your answer to the nearest hundreth
Answer:
.41
Step-by-step explanation:
1ft = 0.000189394mi
0.000189394 x 6mi =0.00113636mi
1 year = 365 days
365 x 0.00113636 =0.41477286
The given speed in miles per year should be 0.41477286.
Given that,
The object speed should be 6 feet per day.Based on the above information, we know that
1 feet = 0.000189394miles
Now there are 6 feet.
So, for 6 feet, the miles should be
= 0.000189394 × 6mi
= 0.00113636mi
Now for per year, it should be
= 365 × 0.00113636
= 0.41477286
Therefore we can conclude that the given speed in miles per year should be 0.41477286.

If -7.6(x - 1) = 7.3 - 7.4x, find the value of -2x.
Answer:
-3
Step-by-step explanation:
Step 1: Write equation
-7.6(x - 1) = 7.3 - 7.4x
Step 2: Solve for x
Distribute -7.6: -7.6x + 7.6 = 7.3 - 7.4x
Add 7.6x on both sides: 7.6 = 7.3 + 0.2x
Subtract 7.3 on both sides: 0.3 = 0.2x
Divide both sides by 0.2: x = 1.5
Step 3: Find -2x
-2(1.5) = -3
Answer:
3
Step-by-step explanation:
-7.6x+7.6=7.3-7.4x
