The answer is like this!

the total number of marbles all together is 25, so that would be the denominator.

blue: 6/25- simplified= already in simplified form
red:10/25- simplified= 2/5
green:9/25- simplified= already in simplified form

so the answer to your question is 2/5.

hope this helped!!

Simplify completely: 8x+4/x^3+23÷4x^2-10x-6/9-x^2
Helen [10]

Answer:

The simplified form is: -x^2-2x+\frac{4}{x^3}+\frac{23}{4x^2}-\frac{2}{3}

Step-by-step explanation:

To simplify the expression given we, need to open the brackets, and if there is power term. Then we need to group all the like terms and then arrange in the descending order of powers of the given expression.

Now the expression that is given to us is:

8x+\frac{4}{x^3}+\frac{23}{4x^2}-10x-\frac{6}{9}-x^2

Here we will simplify it by grouping the like terms, as follows:

8x+\frac{4}{x^3}+\frac{23}{4x^2}-10x-\frac{6}{9}-x^2\\=-x^2+8x-10x+\frac{4}{x^3}+\frac{23}{4x^2}-\frac{6}{9}=-x^2-2x+\frac{4}{x^3}+\frac{23}{4x^2}-\frac{2}{3}

So this is the required simplified form.

CaHeK987 [17]

Answer: 18

Step-by-step explanation:

Let x be the number of 2 point baskets made and y be the number of 3 point baskets made

:

1) x + y = 26

:

2) 2x + 3y = 60

:

solve equation 1 for x and substitute in equation 2

:

x = 26 - y

:

2(26 - y) +3y = 60

:

52 -2y +3y = 60

:

y = 8

:

x = 26 - 8 = 18

:

******************************

The team made 18 2-point shots
