Divide 171 by 3. 57
Therefore the middle integer is 57 
<span>Therefore the highest integer is "2" higher = 59 </span>
<span>The lowest integer is 2 lower to "balance" the higher digit = 55 </span>

<span>Therefore using common sense rather than "let x=....." the answer is 55, 57 and 59.</span>

Your answer is correct it’s 4/33. You first have to convert the mixed number into an improper fraction. Then you’ll have 1/6/11/8 and then you will simplify the complex fraction. I hope that helps!

Neporo4naja [7]

Answer:

x+(3x+2)=30

Step-by-step explanation:

Let

x ----> the length of Zach's car

y ----> the length of Ginny's car

we know that

The sum of the lengths of both cars is 30 inches

so

x+y=30 ----> equation A

Ginny's car is 2 more than 3 times the length of Zach's car

so

y=3x+2 ----> equation B

substitute equation B in equation A

x+(3x+2)=30

Why is a regression line referred to as the line of best fit?
aalyn [17]
<h2>Answer with explanation:</h2>

When there is a linear relationship is observed between the variables, we use  linear regression predict the relationship between them.

Also, we predict the values for dependent variable by modelling a linear model that best fits the data by drawing a line Y=a+bX, where X is the explanatory variable and Y is the dependent variable.

In other words: The line of best fit is a line through a scatter plot of data points that best describes the relationship between them.

That's why the  regression line referred to as the line of best fit.
