I have a few math questions!!?
An old clock loses a minute each day. It is 365 minutes slow after one year of this. How slow is it after two years of this? My answer is 730 minutes and i guarantee that you will get the same but my teacher said it was wrong. is it? It has to be in minutes.
Name the coefficients and constants for the following question:
2x-7 There are 2 coefficients how many constants are there?
Simplify the following question: t – 3t + 2t +4
I got t-9. Am i tight? if i am wrong what is the right answer?
Loryn is flying roundtrip from Dallas, Texas, to Minneapolis, Minnesota. The fare for her ticket is 8. Each airport charges a airport fee. There is also a tax of on the fare. What is the total cost of Loryn’s ticket?
Which two numbers would you combine first to simplify 3 + 6 + 27? Explain.
My answer: It would not matter which one as described in the commutative property. No matter which way you added the numbers together you would still get the answer of 36
What she wrote: Which 2 numbers are easiest to add first? Remember that the commutative property of addition allows you to move the terms around.
Please help! I dont have long!
Simplify just means make it have the least possible steps it can have not actually solve it.
As for the first one it does not say that there will or will not be a leap year. i wrote down exactly what it said

I’m not sure about the first one. All I know is that there are actually 365 and 1/4 days in a year, which is why we have a leap year every four years. I’m not sure if that matters.
There are 2 coefficients? Or the coefficient is 2?
You are wrong. t – 3t + 2t + 4 = 4.
You need to combine the coefficients of the t terms, which is 1 – 3 + 2 = 0. Let’s try plugging in a number for t, like 2. So it would be 2 – 3*2 + 2*2 + 4 = 2 – 6 + 4 +4 = -4 + 4 + 4 = 0 + 4 = 4.
Since Minneapolis is in Minnesota, I assume she’s only stopping off at 3 airports? Anyway, so each airport would charge $16; 3x$16 = $48. $12 for the whole fare so $48 + $12 = $60. Plus $308 for the ticket, so total cost is $368.
I think what your teacher is trying to get at is that the 27 and 3 would be easiest to add first since it easily adds up to 30, a nice round number.
the first one depends if it is a leap year or not in there
