A dinner check is to be split among 3 people. Greg’s portion of the check is twice Kelly’s. Joe’s portion is $1.50 less than 4 t
defon

Answer:

Kelly owes $16.5

Greg owes $33

Joe owes $64.5

Step-by-step explanation:

Let

Kelly's portion = x

Greg's portion = 2x

Joe's portion = 4x - 1.50

Total bill = $114.00

Total bill = Kelly's portion + Greg's portion + Joe's portion

114 = x + 2x + (4x - 1.50)

114 = 3x + 4x - 1.50

114 = 7x - 1.50

Add 1.50 to both sides

114 + 1.50 = 7x - 1.50 + 1.50

115.5 = 7x

Divide both sides by 7

x = 115.5 / 7

= 16.5

x = $16.5

Kelly's portion = x

x = $16.5

Greg's portion = 2x

= 2 × 16.5

= $33

Joe's portion = 4x - 1.50

= 4(16.5) - 1.50

= 66 - 1.50

= $64.5

Therefore,

Kelly owes $16.5

Greg owes $33

Joe owes $64.5

pshichka [43]

Answer:

The equation of the line is y = \frac{3}{5}\cdot x -\frac{26}{5}.

Step-by-step explanation:

Given the values of the slope and a point of the line, we can derive the equation of the line by means of this formula:

y-y_{1} = m\cdot (x-x_{1}) (1)

Where:

x - Independent variable.

y - Dependent variable.

m - Slope.

(x_{1}, y_{1}) - Coordinates of the given point.

If we know that m = \frac{3}{5} and (x_{1},y_{1}) = (2, -4), then the equation of the line is:

y+4 = \frac{3}{5}\cdot (x-2)

y + 4 = \frac{3}{5}\cdot x -\frac{6}{5}

y = \frac{3}{5}\cdot x -\frac{26}{5}

The equation of the line is y = \frac{3}{5}\cdot x -\frac{26}{5}.
