Find the values of x and y using the figure below. Round your answer to the nearest integer.
11111nata11111 [884]

Answer:

x = 11

y = 17

Step-by-step explanation:

5y and (7y - 34) are vertical angles which means they're equal to each other:

5y = 7y - 34

5y - 7y = -34

-2y = -34

y = 17

(8x + 7) and (9x - 4) are also vertical angles:

8x + 7 = 9x - 4

8x - 9x = -4 - 7

-x = -11

x = 11

Which is bigger, -7/12 or -5/9??
sergij07 [2.7K]
Make bottom number same
12=2*2*3
9=3*3
LCD=2*2*3*3=36

-7/12 times 3/3=-21/36
-5/9 times 4/4=-20/36

the farther a number is on the number line to the left, the bigger it is
-20/36 is closer to left

-5/9=-20/36

-5/9 is bigger
