Answer:

Step-by-step explanation:

If you draw a line through each dots, one being from (2,3) to (8,15) and the other being (2,2) to (9,9). And, then if you draw one that is roughly halfway between the two of the first starting points with a slope of 1.5(which is the other 2 lines slopes combined and divided by two to find an average), and then draw out that line to x=9, you will see that it intersects with 13, which is 1 away from 12. Making it the one closest to the line of best fit

Answer:

$51.50

Step-by-step explanation:

Let the amount that Phil give to her sister be $x$

After Phil's sister pays her debt of 10, Phil and her sister should have EQUAL amount. So we can write the equation as:

$93-x=x-10$

Now solving this for x, we have:

$93-x=x-10\\93+10=x+x\\103=2x\\x=\frac{103}{2}=51.5$

Hence, Phil must give $51.50 to her sister.

Answer:

x = 8

Step-by-step explanation:

The marked angles are alternate interior angles, so are congruent.

8x -4 = 60

8x = 64 . . . . . . . . . . add 4 to both sides

x = 64/8 = 8 . . . . . . divide both sides by 8

The value of x is 8.
