Rachel signed up for a frequent-flier program. she receives 4300 frequent-flier miles for her first round trip and 1300 frequent-flier miles each additional round-trip. how many frequent-flier miles will she have after 5 rounds- trips?

Let me show you the procedure: Lets say that  m is frequent flier miles and t is round trips so:m = 1300t + 4300
m = 1300(5) + 4300
m = 6500 + 4300
m = 10800
So she will have 10800 frequent miles

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the answer is 18.
