<em><u>The correct answer is 60 seats on the left side</u></em>, but you might also want to know how I got that answer . . .
Let's say, n = number of rows
Since we know the airplane has an equal number of rows on the right side as it does on the left side, then we can mathematically show that:
number of sears on the right side = 3n = 90 seats
number of sears on the left side = 2n = ? seats
3n = 90
n = number of rows = 90/3 = 30 rows
Thus:
2n = 2(30) = <u><em>60 seats on the left side</em></u>
<em>as for how many seats all together, just add . . 90 + 60 = 150 seats total</em>

Answer: 8 + 2/3 batches of brownies you can bake.
Step-by-step explanation:
6 1/2 butter = 6 + 1/2 = (2·6 + 1)/2 = 13/2 sticks of butter, we have this
Since we have 13/2 sticks of butter and each batch of brownies needs 3/4 of a stick of butter, we have to divide the amount of butter we have between the amount of butter we use to bake a batch of brownies.
13/2 butter ÷ 3/4 butter/batch = 13·4/2·3 batches = 52/6 batches = 8 + 2/3 batches
Answer: 8 + 2/3 batches of brownies you can bake.
