Question

HELP ASAP!! Someone please help me solve #19 with steps on how to solve?

Answer 1

Answer:

a.9

b. ay=9

xy= 18

Step-by-step explanation:

a. xa=ay (since a is a midpoint that means xa and ay are the same amount).

3x=5x-6

subtract 5x from both sides

-2x=-6

inverse operations, so divide both sides by -2. (a negative divided by a negative is a positive)

x=3

so xa=3x. fill in x

3*3 is 9

b. fill in the x

5*3-6

5 times 3 is 15.

15-6=9

(also xa is 9 and they are congruent so both are 9)

ay= 9

add both sides to find xy

9+9=18

xy=18
