Answer: 6 pieces

=======================================================

Explanation:

3/4 = 6/8 after multiplying both parts by 2

We have a ribbon that is 6/8 of an inch long. We want to cut it into 1/8 inch pieces. We can see there will be exactly 6 pieces

Note how 6*(1/8) = 6/8

Or we can think of it as "we have a ribbon that is 6 units long and we want to cut it into pieces that are 1 unit each, so we'll have 6 pieces total". Replace "unit" with "1/8 inch" and you'll have the same idea.

Answer:

6 pieces

Step-by-step explanation:

1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 6/8 = 3/4

For what value of x is line m parallel to line n?

kogti [31]

Answer:

$x=10$

Step-by-step explanation:

Here, we can use an angle rule.

We see that angles $(8x+50)$ ° and 130° are under a sort of F shape, where lines m and n are the horizontal parts of the letter and where the diagonal line is the vertical part of the letter.

This means we can use the rule:

Corresponding angles are equal.

This means that:

$8x + 50 = 130$

We can now use this equation we have formed to solve for $x$ :

$8x + 50 = 130\\8x = 80\\x = 10$

Therefore, our final answer is $x=10$ .

A line of best fit predicts that when x equals 30, y will equal 34.215, but y actually equals 32. What is the residual in this c

Katarina [22]

Answer: A. - 2.215

Step-by-step explanation:

• A residual is the difference between the actual value and the predicted value in a regression model. It represents the vertical distance from the actual point to the point on the regression line.

$\text{Residual=Actual value of y -predicted value of y}\\\\\Rightarrow\text{Residual}=32-34.215\\\\\Rightarrow\text{Residual}=-2.215$

Hence, the residual in this case = -2.215

A system of equations is shown below:

ivolga24 [154]

To solve this problem you must apply the procceddure shown below:

1. You have the following system of equations:
<span>
x+y = 3
2x–y = 6

2. Then, you must clear the variable y from the first equation and susbtitute it into the second equation, as below:

x+y=3
y=3-x

2x-y=6
2x-(3-x)=6
2x-3+x=6
3x=6+3
3x=9

3. Therefore, the value of x is:

x=9/3
x=3

4. As you can see, the correct answer is:

x=9
