Answer:
x = ZERO
Step-by-step explanation:
In the picture above.
If you want to check, just substitute the value of x in the equation .
The value of 2¹²/₁₃, rounded to the nearest tenth, is approximately 2.9.
To write 2¹²/₁₃ as a decimal rounded to the nearest tenth, we need to convert the mixed number to an improper fraction first and then divide the numerator by the denominator.
The mixed number 2¹²/₁₃ can be written as an improper fraction as follows:
2¹²/₁₃ = (2 x 13 ) + 12) / 13 = 38/13
Now, we can divide the numerator (38) by the denominator (13) to convert the fraction to a decimal:
38 ÷ 13 = 2.92307692308...
Rounding to the nearest tenth means we consider the digit in the tenth place and decide whether to round up or down based on the next digit (in the hundredth place).
In this case, the digit in the tenth place is 9, and the next digit (in the hundredth place) is 2. Since 2 is less than 5, we round down.
Therefore, rounding 2.92307692308... to the nearest tenth gives us:
2.9
So, 2¹²/₁₃, rounded to the nearest tenth, is approximately 2.9.

In order to write 2 12/13 to a decimal, you must divide 12 by 13. 12 divided by 13 is 0.923. However, you must add the whole number making it 2.923. Yet, you must round it to the nearest tenth. 9 is in the tenths place meaning we rely on 2. 2 is less than 5 meaning we round down. The answer is 2.9.
running at the same rate?
We want to create a proportion with minutes over miles for each person. The proportion for this problem is shown below.
30 minutes / 4 miles = 56 minutes / 7 miles
To find out if these people are running at the same rate, we can cross-multiply.
224 = 210
Because 224 and 210 are not equivalent, the people are not running at the same rate.
Hope this helps!! :)
