Answer:

Step-by-step explanation:

Given that at the end of a math contest, each team must select two students to take part in the countdown round. As a math

team coach, you decide to randomly select two students from your team. You would prefer that the two students

selected consist of one girl and one boy.

If we have 6 girls and 6 boys, one girl can be selected in 6 ways and one boy also in 6 ways

No of ways = 36

Instead, If we have 5 girls and 5 boys, one girl can be selected in 5 ways and one boy also in 5 ways

No of ways = 25

First group is better as we have more choices to select the best one from each set of girl and a boy.

Three times x less than y is five times y plus two times x in a verbal sentence please help
tankabanditka [31]
SOLUTION:

As an equation it is:

y - 3x = 5y + 2x

If you are asking for it as a sentence ( I will do it as a written sentence as I unfortunately can't show you the sentence verbally as you had asked ), then it is as you had written in your question so:

Three times x less than y is five times y plus two times x

Or you could write is as:

y subtracted by three times x is equivalent to the sum of five times y and two times x.

Essentially, even with the small alterations that you can make to the phrasing and sentence structure, the concepts are the same so you can use one of the above answers or alter it as you please.

Hope this helps! :)
