(a+b+c)/2. this is your answer. if it had the numbers i would solve it fully, but it only has variables.
Answer:
answer is 1/4
Step-by-step explanation:
proof is (x-1/2)²= x²-2*1/2*x+1/4= x²-x+1/4
Answer: x=-10, y=13
Step-by-step explanation:

+2y-2y = 0, eliminating y is much easier. So -3x-5x = -8x and 56+24 = 80

Substitute x in any equations but only 1 equation (Don't substitute in both equations.)
For me, I'd substitute x in -3x+2y=50

So the answer is x = -10, y = 13
16a^18 is the answer for what you typed
If the question was ((2a^3)(4a^6)(2a^3))^6, then the answer would be 16a^72.
This is very simple.
If you want 4.35 pounds, and it's 2.29 a pound, you simply multiply 4.35 by 2.29.
4.35 * 2.29 = 9.9615 or 10
The chicken salad costs $9.9615 or $10, whichever you need.
