Answer: b+95+34=180, b+129=180, 51
Step-by-step explanation:
b+95+34=180 works because the angles add to form a straight angle.
From this, we can obtain b+129=180 by adding the two constants.
Subtracting 129 from both sides, we get b=51.
Okay, lets start with number 1.
is also equal to (x+3)(x+3)(x+3)
If you take the first two ones and multiple them out it ends up with 
or also know as 
You see to multiply them you take the first number in the first group of parenthesis and use the distributive property on the second equation, then you do the same this but with the second number in the first equation.
So once you have 
you multiply it with your remaining (x + 3) using the distributive property to get 
I hope this helps you get the answers for the other two.
3/x=5/y multiply both sides by y
3y/x=5 divide both sides by 3
y/x=5/3
The answer would be 242.8
It will not go up because in order to round up it must be 5 or above.
Answer:
-1/2
Step-by-step explanation:
I used rise/run it went 1 unit down and 2 units to the right from point to point and since we are going down its negative
