Answer:

17. 10

Step-by-step explanation:

1. A segment going from an endpoint to the midpoint of the original segment is going to be 1/2 of the original segment.

AM = 1/2 AB

2. You know that the length of AM is 5, so plug that in a solve algebraically

5 = 1/2 AB

(2)5 = (2) 1/2 AB

10 = AB

Answer:

18. 30

Step-by-step explanation:

The sum of two segments spanning from the original segment's midpoint to the end equals the length of the original segment. Because the midpoint is exactly in the middle of the original segment, the two other segments should equal each other.

1. You need to first find the length of the two segments by setting them equal to each other and plugging in their equations.

5x = x+12

2. Solve algebraically

5x = x+12

4x = 12

x = 3

3. Plug z into the equations for each segment and add them together.

RM = 5(3) MS = (3)+12

RM = 15 MS = 15

15+15 = 30

Which of the ordered pairs in the form (x, y) is a solution of this equation? 5x-y/3 = 13 (2, -9), (3, -6)

zalisa [80]

C. The first is a solution, but the second is not.

5x - y/3 = 13 ; (2,-9)
substitute the letters:
5(2) - (-9/3) = 13
10 - (-3) = 13 : note that deducting a number with a negative sign turns both sign as positive.
10 + 3 = 13 ;
13 = 13

5x - y/3 = 13 ; (3,-6)
5(3) - (-6/3) = 13
15 - (-2) = 13
15 + 2 = 13
17 = 13 not equal. not a solution

Factor completely<br> 486+108x+6x^2<br><br> Thank you!

viktelen [127]

Answer:

6(x + 9) (x + 9)

$6 (x+9)^{2}$

Step-by-step explanation:

$468 + 108x + 6x^{2} \\6x^{2} +108x + 468$

Greatest common factor of 6, 108, and 486:

6 x 1 = 6

6 x 18 = 108

6 x 81 = 486

GCF: 6

so:

$6(x^{2} +18x +81)$

$x^{2} +18x + 81$

factors to:

(x + 9) (x + 9)

because:

9 x 9 = 81

9 + 9 = 18

So:

It factors completely too:

6(x + 9) (x + 9)

$6 (x+9)^{2}$

If 2x+1/4 = 12/20 what is the value of x

ExtremeBDS [4]

Answer:

7/10 or 0.7

Step-by-step explanation:

cross multiply to get 40x+20=48

subtract 20 from both sides to get 40x=28

divide both sides by 40 to get 7/10

HOPE THIS HELPS!!!:)
