Answer:

Since the spinners have been spun simultaneously, every side on each of the spinner carries equal probability of landing. In order for there to be only 10 possible outcomes, no more no less, the spinners cannot be identical. One of the spinner in two sided while the other spinner must then be a five sided spinner. Choosing this particular pair of spinners gives Nathan 10 possibilities of combinations.

Hope that answers the question, have a great day!

The equivalent expression = 1/12 of a mile

Step-by-step explanation:

Total distance of 10 members of the Balin's soccer club =5/6 of a mile

To find the distance that each member ran, Balin wrote the expression:

5/6 ÷ 10

Which expression is equivalent to Balin's expression?

5/6 ÷ 10

= 5/6 × 1/10

= 5/60

= 1/12 of a mile

Each member of the Balin's soccer club ran 1/12 of a mile

The equivalent expression to 5/6 of a mile divided by 10 members of the Balin's soccer club is 1/12 of a mile

Step-by-step explanation:

Answer:

Let's solve for x.

5x−4y=−23−5x+9y

Step 1: Add 5x to both sides.

5x−4y+5x=−5x+9y−23+5x

10x−4y=9y−23

Step 2: Add 4y to both sides.

10x−4y+4y=9y−23+4y

10x=13y−23

Step 3: Divide both sides by 10.

6) The solution set of the equation x² + 8x - 15 = 5x + 13 is {-7, 4}.

7) The zeroes of the expression 2x (x - 5) (x + 7) are {-7, 0, 5}.

8) The expression (x + 5) (x + 8) + (x + 5)(2x - 3) can be written as a product of (x + 5) and (3x + 5).

9) There are 2 integer solutions on the interval 0 ≤ x ≤ 10 for the equation x³ - 5x² + 2x + 13 = 5.

We have,

6)

x² + 8x - 15 = 5x + 13

Rearranging the equation:

x² + 8x - 5x - 15 - 13 = 0

x² + 3x - 28 = 0

Now, factorize the quadratic equation:

(x + 7)(x - 4) = 0

Setting each factor equal to zero:

x + 7 = 0 or x - 4 = 0

Solving for x:

x = -7 or x = 4

7)

2x (x - 5) (x + 7) = 0

Setting each factor equal to zero:

2x = 0 or x - 5 = 0 or x + 7 = 0

Solving for x:

x = 0 or x = 5 or x = -7

8)

(x + 5) (x + 8 + 2x - 3)

Simplifying the expression inside the parentheses:

(x + 5) (3x + 5)

9)

x³ - 5x² + 2x + 13 = 5

Substitute each integer value from 0 to 10 into the equation and count the number of solutions.

Substituting each integer value,

x = 0,

x³ - 5x² + 2x + 13 = 5

0 - 0 + 0 + 13 = 5

13 = 5

Not true.

Similarly,

x = 2,

x³ - 5x² + 2x + 13 = 5

8 - 20 + 4 + 13 = 5

25 - 20 = 5

5 = 5

True.

x = 4,

x³ - 5x² + 2x + 13 = 5

64 - 80 + 8 + 13 = 5

85 - 80 = 5

5 = 5

True.

There are two integer solutions:

x = 2 and x = 4.

Therefore,

The solution set of the equation x² + 8x - 15 = 5x + 13 is {-7, 4}.

The zeroes of the expression 2x (x - 5) (x + 7) are {-7, 0, 5}.

The expression (x + 5) (x + 8) + (x + 5)(2x - 3) can be written as a product of (x + 5) and (3x + 5).

There are 2 integer solutions on the interval 0 ≤ x ≤ 10 for the equation x³ - 5x² + 2x + 13 = 5.

Answer:

Step-by-step explanation:

14 x + 5y = 329

11x + 5y = 281(vans is x and busses are y)

cancel out 'y' by making the '5y' in 11x + 5y = 281 negative

-1 (11x + 5y = 281) =

-11x -5y = -281

insert second equation

-11x -5y = -281

14x + 5y = 320

3x = 48

x = 16

substitute vans in one equation

11(16) + 5y = 281

5y = 105

y = 21

Step-by-step explanation:

The independent variable is m the number of minutes a hose runs.

The dependent variable is g the number of gallons the hose sprays.

The number of gallons a horse sprays depends on the minutes the hose runs. Lets say the hose sprays a gallon in a minute. And let us say the hose runs for 5 minutes. That would mean the hose would have sprayed 5 gallons of water.

The minutes a hose runs does not depend on the gallons the hose sprays.
