T=d/v
540/(230+w)=380/(230-w)
540(230-w)=380(230+w)
124200-540w=87400+380w
124200-920w=87400
-920w=-36800
w=40
So the wind speed is 40 miles per hour.
Answer:
Step-by-step explanation:
100-10 : 100
90 : 100
504 : x
x=540x100/90
x=50400/90
x=560
Answer:
In order of what is shown on the pic:
- Trinomial
- Monomial
- Trinomial
- Binomial
- Polynomial with four terms
Step-by-step explanation:
Again, in the same order as above:
1. The first has three terms, making it a trinomial
2. 7x^2 - 7x^2 +4x
The 7x^2 cancels out and we are left with only 4x
Since there is one value, it is a monomial
3. This one has three terms, making it a trinomial
4. This one has two terms, making it a binomial
5. The last one has four terms, making it a polynomial with four terms.
Answer:
Step-by-step explanation:
Set it up as fractions, Alex over Peter.
3/5 : 33/x Let x represent Peter's amount. Now find out: how do you get from 3 to 33? What times 3 equals 33? 11
What you do on the top, you must do on the bottom. If 3 times 11 equals 33, then 5 times 11 equals x. 5 times 11 equals 55, so x equals 55.
Peter will get 55. Don't forget the pound symbol.
