Answer:

David's score= 160 ;  Aaron's score = 55

Step-by-step explanation:

let Aaron's score be 'x'.

so, David's score will be 3x - 5

(3x - 5) + x = 215

3x + x - 5 = 215

4x = 215 + 5

4x = 220

x = 220/4

x = 55

therefore, Aaron's score = 55

David's score is (3x - 5) = (3*55) - 5 = 165 - 5 = 160

Answer:

son = 10 , father = 40

Step-by-step explanation:

Let Five years ago the age of son be x years and age of father be 7x years

Present age of son =x+5

Present age of father =7x+5

5 years later their age will (x+10) and (7x+10)

∴7x+10=3(x+10)

7x−3x=20

4x=20

x=5

So, the present age of son=x+5=5+5=10years

and the present age of father=7x+5=35+5=40years

hope it helps you

Which of the following point-slope form equations could be produced with the points (-1, 4) and (2, -3)?
Nikolay [14]

Answer:

Option B, y + 3 = -7/3(x - 2)

Step-by-step explanation:

<u>Point slope form:  (y - y1) = m(x - x1)</u>

<u />

<u>Step 1:  Find the slope</u>

m = \frac{y2 - y1}{x2 - x1}

m = \frac{-3 - 4}{2 - (-1)}

m = \frac{-7}{2 + 1}

m = \frac{-7}{3}

<u>Step 2:  Plug into the point slope form</u>

(y - 4) = -7/3(x - (-1))

(y - 4) = -7/3(x + 1)

OR

(y - (-3)) = -7/3(x - 2)

y + 3 = -7/3(x - 2)

Answer:  Option B, y + 3 = -7/3(x - 2)
