Answer:

The coach can do this in 3,003 ways

Step-by-step explanation:

Here, the coach needs to select a team of 5 from a total of 15 players

Mathematically, the number of ways this can be done is simply 15 C5 ways

Generally, if we are to select a number of r items from n items, this can be done in nCr ways = n!/(n-r)!r!

Applying this to the situation on ground, we have;

15C5 = 15!/(15-5)!5! = 15!/10!5! = 3,003 ways

Write the expanded form of the expression. <br> -1/2 (y - x) = ?
morpeh [17]

Answer:

The expanded form of the expression -\frac{1}{2}(y-x) is \mathbf{-\frac{1}{2}(y)+\frac{1}{2}(x)}

Step-by-step explanation:

We need to write expanded form of the expression -\frac{1}{2}(y-x)

For expansion we will use distributive property of multiplication over addition

a(b+c)=ab+ac

Applying above rule:

-\frac{1}{2}(y-x)\\=-\frac{1}{2}(y)-(-\frac{1}{2}(x))\\=-\frac{1}{2}(y)+\frac{1}{2}(x)

So, the expanded form of the expression -\frac{1}{2}(y-x) is \mathbf{-\frac{1}{2}(y)+\frac{1}{2}(x)}

The ratio of the price of a pair of sneakers to the price of a pair of boots is 15:19. The price of a pair of boots is 570 dolla
Genrish500 [490]

Answer:

$1470

Step-by-step explanation:

sneakers : boots

15 : 19


15        cost sneakers

------ =  -------------------

19          570


using cross products

15 * 570 = 19 * sneakers

8550=19 * sneakers

divide by 19

8550/19 = sneakers

sneakers = 450

total cost = 2* sneakers + boot

total cost = 2 * 450 + 570

total cost = 900 + 570

total cost = 1470

Help please if it was u u would want the same so please help
antiseptic1488 [7]
Simple...

you have: 8x-6y=1

You're trying to find m-->>using y=mx+b to re-write the line....

8x-6y=1

8x-6y=1
-8x      -8x

-6y=-8x+1

\frac{-6y}{-6} = \frac{-8x+1}{-6}

y=\frac{4}{3} x- \frac{1}{6}

Your slope m=\frac{4}{3} x

Thus, your answer.
