Travka [436]

Answer: 20%

Step-by-step explanation:

The probability that a randomly selected marble will be pink can be found by the formula:

= Number of pink marbles / Number of total marbles

= 4 / 20

= 20%

What is the slope of the line through (-1,4) and (5,2)
butalik [34]

Answer:

Slope (m) = -\frac{1}{3}

Step-by-step explanation:

Use the following equation:

Slope (m) = \frac{y_2 - y_1}{x_2 - x_1}

Let:

(x_1 , y_1) = (-1 , 4)\\(x_2 , y_2) = (5 , 2)

Plug in the corresponding numbers to the corresponding variables:

m = \frac{2 - 4}{5 - (-1)} = \frac{2 - 4}{5 + 1} = \frac{-2}{6}

Simplify. Divide common factors from both the numerator and denominator:

\frac{(-\frac{2}{6})}{\frac{2}{2} } = -\frac{1}{3}

-\frac{1}{3} is your answer.

uysha [10]

Answer: x=45

<u>Simplify both sides of the equation</u>

<u></u>x+1.2x+1=100

(x+1.2x)+(1)=100 (Combine Like Terms)

2.2x+1=100

<u>Subtract 1 from both sides</u>

<u></u>2.2x+1-1=100-1\\2.2x=99<u></u>

<u></u>

<u>Divide both sides by 2.2</u>

<u></u>2.2x/2.2=99/2.2<u></u>

<u></u>x=45<u></u>
