Alan is 14 years old. he is twice as old as his brother James. how old is James?
Degger [83]

Alan is 14 years old

He is twice as old as James

then Alan is the elder brother

Alan is twice as old means his age is double the age of James

Alans age = 2 x james age

that means James must be half of Alans age

Alans age = 14 years

James age = 14 / 2 = 7 years

therefore James is 7 years old

<h3 /><h3>\huge \rm༆ Answer ༄</h3>

To find slope we use the formula ~

  • \sf \dfrac{y2 - y1}{x2 - x1}

[ Ratio of the difference of y - coordinates of the points and the difference of x - coordinates of the points ]

let's find the slope of line passing through the given points ~

<h3>1. (10 , -9) and (-4 , -14) </h3>

  • \sf \dfrac{ - 9 - ( - 14)}{10 - ( - 4)}

  • \sf \dfrac{ - 9 + 14}{10 + 4}

  • \sf \dfrac{5}{14}
<h3>2. (16 , 6) and (-4 , -14)</h3>

  • \sf \dfrac{6 - ( - 14)}{16 - ( - 4)}

  • \sf \dfrac{6 + 14}{16 + 4}

  • \sf \dfrac{20}{20}

  • \sf1
<h3>3. (9 , -4) and (5 , -20)</h3>

  • \sf \dfrac{ - 4 - ( - 20)}{9 - 5}

  • \sf \dfrac{ - 4 + 20}{4}

  • \sf \dfrac{16}{4}

  • \sf4

<h3>4. (-13 , 20) and (-18 , 20)</h3>

  • \sf \dfrac{20 - 20}{ - 13 - ( - 18)}

  • \sf\dfrac{0}{ - 13 + 18}

  • 0

I hope it helps ~
