Answer:
use Pythagoras theorem to find hypotenuse in right angle triangle
Step 1. Add 6 to both sides
a ≥ 1 + 6
Step 2. Simplify 1 + 6 to 7
a ≥ 7
- 3x + 4y = - 11
y = 2x - 4
-3x + 4(2x - 4) = -11
-3x + 8x - 16 = - 11
5x = -11 + 16
5x = 5
x = 5/5
x = 1
y = 2x - 4
y = 2(1) - 4
y = 2 - 4
y = -2
Solution: (1, -2)
Answer:
174 people preferred drinking water.
Step-by-step explanation:
Given that:
A total of 450 males and females were surveyed.
203 were males.
Number of females = 450 - 203 = 247 females
247 females were surveyed.
Now, we will find the number of females who prefer water.
Let,
x be that number.
Total number of females = Soda + Iced tea + Lemonade + Water
247 = 28 + 44 + 67 + x
247 = 139 + x
247-139 = x
x = 108
Number of people who prefer water = 108 + 66 = 174
Hence,
174 people preferred drinking water.
