You subtract the  2 given sides from the perimeter so its

7a - 11b - (2a + b) - (a - 9b)    ( Note the 2 sides must be in parantheses)

= 7a - 11b - 2a - b - a + 9b 

adding like terms:-

= 4a - 3b

6 - 2y + (-8y) + 5.1 = 0<br> (Simplify your answer. Use integers
Nadusha1986 [10]

Answer:

Simplified answer = 11.1 - 10y = 0

y = 1.11

Step-by-step explanation:

6 - 2y + (-8y) + 5.1 = 0

6 + 5.1 -2y -8y = 0

Add like terms

11.1 - 10y = 0

(This is simplified, but if you want to solve for y, continue)

11.1 - 10y = 0

÷10  ÷10

1.11 - y = 0

y = 1.11 because 1.11 - 1.11 is 0

I Hope That This Helps!
