<span>add 2/9x to both sides, if you do that you get 2/9x+y=3. If you want to simplify it multiply everything by the denominator, in this case, 9 so then you would have 2x+9y=27
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Answer:
120 blocks total
Step-by-step explanation:
All of the little cubes have side length 2" Thus, the 11" height of the box cannot be used entirely: we waste the top 1" because the five layers of little cubes reach only to 10" from the bottom.
Start at the bottom of the box. The dimensions of the bottom are 12" by 8". Along the longer side we can lay 6 blocks (which add up to 12" and are 2" wide. We can add 3 more such rows to fill the available 8" width of the box bottom. That's 6*4, or 24 blocks.
We can add 4 more 6 block by 4 block layers before we have the maximum 5 layers stacked in the box.
5 layers times 24 blocks per layer comes to 120 blocks total.
Let a be an apple, b be a baseball, p be a pineapple and s be a shoe.
Then, from the balance, we model these equations:
p + b = s ----- (1)
2s = 4a
Divide both sides by 2.
s = 2a
Substitute in (1), we get,
p + b = 2a ----- (2)
Also,
p = a + b ----- (3)
Substitute the above in (2), we get,
(a + b) + b = 2a
a + 2b = 2a
Subtract a from both sides.
a = 2b
Substitute in (3), we get,
p = 2b + b = 3b
Hence, 3 baseballs equal one pineapple.
Answer:
Price Discrimination OR Law of Demand; according to the complete question.
Step-by-step explanation:
24% of the students in the first group answered yes.
73% of the students in the second group answered yes.
More students in the second group were willing to pay $75 for the pair of jeans BECAUSE they were told that the normal price was much higher.
From this information, I guess that the first group was told (by the jeans vendor probably) that the $75 was higher than the normal price of the jeans. This will be the reason why a lesser percentage of students in Group A are willing to purchase the pair of jeans.
This is an example of PRICE DISCRIMINATION effect on decision making. Price discrimination is used in product marketing.
The same pair of jeans in Situation A cost higher than the normal price while in Situation B it cost lower than the normal price. Even though the figure given is static at $75 in both cases, the data that follows in the question tells it as 2 different prices; one favourable to the buyers and another not so favourable to the buyers.
The LAW OF DEMAND also applies here. The higher the price, the lesser the quantity demanded (by a group of students) and the lower the price, the higher the quantity demanded.
