So let’s say you have (2,8) and (4,12)
Your x values are your first ones. So 2 and 4.
that formula is to find the midpoint so let 2 by x1 and 4 be x2. Add those together you get 6. Then divide by 2. Always by 2. You get 3. That’s the midpoint of those two points. Same thing for the y values.
Answer:
Step-by-step explanation:
Let x be the added 20% solution.
<u>The salt content is same:</u>
- 50*0.6 + x*0.2 = 0.28*(x + 50)
- 30 + 0.2x = 0.28x + 14
- 0.28x - 0.2x = 30 - 14
- 0.08x = 16
- x = 16/0.08
- x = 200
Fifteen times Fifteen point Five equals 82.2 so the answer would be 82.2 Meters
Answer:
Step-by-step explanation:
y=-\frac{1}{2}x+\frac{11}{2}
Area = length x width
area = 2 3/4 x 2/5
area = 1 1/10 feet :)
