Are these the answer choices. If so I would say D
We need the following to be true
a+2b = -a
a+4 = 2a - 3b
Let's look at the first equation.
a + 2b = -a
Subtract both sides by a
2b = -2a
b = -a
Substitute b= -a into the second equation
a+4 = 2a + 3a
a + 4 = 5a
4a = 4
a = 1
Just take the negative of that and you get the value of b.
b = -1
Your solution is a=1 and b = -1.
Have an awesome day! :)
Angles 2, 6, and 7 because angle 1 = 115 so that makes angle 4 = 115 so angle 2 must also be 65 so angle 4 and 2 = 180 and the same goes for angles 5,6,7,8
Yes... indeed it is 1/8 because
125/1000 In simplest form is 1/8
