First, look at how many numbers are divisible by 2 and 3. 
12,72, and 108 and are all divisible by both 2 and 3. That makes 3 out of 8 numbers.
Depending on what form you have to put the probability, that makes it 3:8, 3 out of 8, or 37.5% probability.

To multiply a fraction, you simply multiply across the top and across the bottom.

-3 *-4 = 12
5 * 7 = 35

Final Answer: 12/35

MATH HELP!!!!!<br><br> If y = 15 when x = 2, what is the value of x when y = 7?
Ede4ka [16]

<u>Direct Variation:</u>  \frac{y}{x} = k

\frac{15}{2} = k

when y = 7:      \frac{7}{x} = \frac{15}{2}

14 = 15x

\frac{14}{15} = x

<u>Inverse variation:</u>   y*x = k

15 * 2 = k

30 = k

when y = 7:      7 * x = 30

x = \frac{30}{7}

​Combined, there are ​Asians, Africans,​ Europeans, and Americans in a village. The number of Asians exceeds the number of Afric
yanalaym [24]

There are 123 Asians, 25 Africans, 21 Europeans and 8 Americans in the village.

To determine the number of Asians, Africans, Europeans, and Americans in the village, the following calculation must be performed:

 

  • A.S + A.F + E.U + A.M = 177
  • A.S = A.F + E.U + 69
  • E.U - A.M = 13
  • E.U = A.M + 13
  • 2A.F = E.U + A.M + 29
  • A.F + E.U + 69 + A.F + E.U + A.M = 177
  • A.F + A.M + 13 + 69 + A.F + A.M + 13 + A.M = 177
  • 2A.F + 3A.M = 177 - 13 - 13 - 69
  • E.U + A.M + 29 + 3A.M = 82
  • A.M + 13 + A.M + 29 + 3A.M = 82
  • 5A.M = 82 - 13 - 29
  • A.M = 40/5
  • A.M = 8
  • E.U = 8 + 13 = 21
  • A.F = (21 + 29) / 2 = 25
  • A.S = 177 - 25 - 21 - 8 = 123

Therefore, there are 123 Asians, 25 Africans, 21 Europeans and 8 Americans in the village.

Express the following equation in slope-intercept form: 13x - 3y = 18 Select the best answer from the choices provided. A. y = 3
AveGali [126]

Answer:

The equation in the slope-intercept form is y =  \frac{13}{3}x + -6 ⇒ C

Step-by-step explanation:

The slope-intercept form of the linear equation is

y = m x + b, where

  • m is the slope of the line
  • b is the y-intercept

∵ The equation is 13x - 3y = 18

→ At first move x from the left side to the right side by subtracting 13x

  from both sides

∴ 13x - 13x - 3y = 18 - 13x

∴ - 3y = 18 - 13x

→ Make the coefficient of y equal 1 by dividing both sides by -3

∵ \frac{-3y}{-3}=\frac{18}{-3}-\frac{13x}{-3}

∴ y = -6 - (-\frac{13}{3}x)

→ Remember (-)(-) = (+)

∴ y = -6 + \frac{13}{3}x

→ Switch the two terms of the right side

∴ y =  \frac{13}{3}x + - 6

∴ The equation in the slope-intercept form is y =  \frac{13}{3}x + -6
