Answer:
y/2 = 4.5
Step-by-step explanation:
1/4x + 2y = 11/4
distribute by 4 to eliminate fractions
x + 8y = 11
+ <u>-x - 6y = 7</u>
2y = 18
y = 9
half of 9 = 4 1/2
Answer:
False
Step-by-step explanation:
Actually, the arithmetic average (or mean) is always greater or equal than the geometric average. This is known as the Arithmetic-Geometric inequality (AM inequality). Let a,b be two real numbers, then the AM inequality states that
To see that the given statement is false, consider a=1, b=3. The arithmetic mean is equal to (1+3)/2=2, and the geometric mean is equal to but , contrary to the statement (arithmetic>geometric in this case).
