1 answer:
Answer:
Lourdes has more brownies.
Step-by-step explanation:
First, you have to find a common denominator. Whatever you do to the bottom of the fraction you do to the top. 5/6 and 4/5 has a common denominator of 30. Multiply both digits in 5/6 by 5. Then multiply both digits in 4/5 by 6. Then you can compare the fractions. With the common denominators, Lourdes should have 25/30 brownies and Zachary has 24/30. Compare.
24/30 < 25/30. So Lourdes has the most brownies!

Answer:
k = 18
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 3 when x = 6, that is
3 = ( multiply both sides by 6 )
18 = k
The constant of variation is k = 18
