I'm guessing you're trying to simplify the equation since there is no other information lol
[(2x+y)-3]
So basically when you are trying to simplify equations you have to add the same variables together (In this case X & Y) But since there are no alike variables there really is nothing to add
So your answer would be 2x+y-3
Hoped this helped
Answer:
Step-by-step explanation:
Given:
(segment addition postulate)
(substitution)
(subtracting 17 from each side)
(Subtracting 5y from both sides)
(dividing both sides by -2)
Plug in the value of y
Answer:
x = 3*n (whatever age she was 6 years ago)
or
3*n = x
Sector C is 35% of the circle, so it will be 35% of the degrees of a full circle, which is 360.
Multiplying something by .35 gives you 35% of the number, so do that with 360.
360 x .35 = 126
The angle is 126º.
Hope this helps!
