Answer:
8x > 9y
Step-by-step explanation:
Since the first hen laid 8 eggs a week, the amount of eggs can be represented by 8x.
The second hen laid 9 eggs a week, so it can be represented by 9y.
The first hen laid more eggs than the second hen, so use a greater than inequality.
Put this all together:
8x > 9y represents this relationship
Answer:
50 cards
Step-by-step explanation:
We can start by saying that his total card collection has x cards in it, meaning that 28% or 28/100 of his total cards, x, is equal to 14. Next, we can divide by 28/100 on both sides, and dividing is the same as multiplying by the reciprocal. The reciprocal of 28/100 is 100/28, so 14 * 100/28 is equal to 100/2, which is 50. We can say that 50 cards were in his card collection initially.
Hey, there are no numbers added to this problem but if you were to add them as I did down below that is how you solve this question!
Step-by-step explanation:
Suppose s and h are the mileage numbers for the SUV and Hybrid, respectively. Then if each vehicle drives 1 mile, the total gas consumption is
.. 1/s +1/h
Then the combined mileage is
.. 2/(1/s +1/h) = 2sh/(s+h)
Option 1: s=12, h=60
.. mpg = 2*12*60/(12+60) = 20
Option 2: s=11, h=75
.. mpg = 2*11*75/(11 +75) = 1650/86 ≈ 19.2
In summary,
.. Option 1: 20.0 mpg
.. Option 2: 19.2 mpg
