Mathematics
1 answer:
vlada-n [284]2 years ago

Answer:

11. 16x +(9x+5)= 180

25x + 5 = 180

25x= 175

x= 7

If x is 7, then the top value is equal to the bottm one becuase they are vertical angles.

112 + 4y= 180

4y = 68

y= 17

Step-by-step explanation:

12. 6x - 11 + 2x - 9= 180

8x - 20= 180

8x= 200

x= 25

6(25) - 11= 139

20y + 19 = 139

20y = 120

y=6

What is the solution to the system of equations?<br><br> y = –5x + 3<br><br> y = 1
Alinara [238K]
Ok so we know that y=1 so we can simply sub in the value of y into the equation :

y = -5x +3

1 = -5x +3

Move the -5x to the LHS ( Left-hand-side ) therefore it changes sign as well move 1 to the RHS ( Right-hand-side ) it also changes sign.

5x = 3 - 1

5x = 2

x = 2/5

x = 0.4

Hope this helps :).
