-5x - 3(-4x - 9) = 83
Add 5x to both sides
-3(-4x-9) = 83 + 5x
Divide by -3
-4x-9 = 83/3 + 5/3x
Subtract 5/3x
-4x -5/3x -9 = 83/3
Add 9
-17/3x = 110/3
Multiply by 3
-17x = 110
Divide by -17
X = 6 and 8/17

-5x-3(-4x -9)= 83

Distribute. 

-5x+12x+27= 83 (two negatives equal a positive) 

Combine like terms.

7x+27= 83

Subtract 27 from both sides.

7x= 56

Divide 7 into both sides.

x=8

I hope this helps!

A ride-share company has a fee that includes a fixed cost and a cost that depends on both the time spent travelling, in minutes,
zlopas [31]

Answer:

the cost of Roy's ride is $23.05

Step-by-step explanation:

According to the Question,

Let, Cost of per minute charge is 'x' & Cost Of Per Kilometre charge is y .

  • Given, A ride-share company has a fee of the fixed cost of a ride is $2.55 .
  • And, The Total cost of the Ride depends on both the time spent on travelling(in minutes), and the distance travelled(in kilometres) .

⇒ Judy's ride costs $16.75 . but the actual cost after deducting the fixed charge is 16.75-2.55 = $14.20, took 8 minutes & The distance travelled was 10 km. Thus, the equation for the journey is 8x+10y=14.20 ⇒ Equ. 1

⇒ Pat's ride costs $30.35 . but the actual cost after deducting the fixed charge is 30.35-2.55 = $27.80, took 20 minutes & The distance travelled was 18 km. Thus, the equation for the journey is 20x+18y=27.80 ⇒ Equ. 2

Now, on Solving Equation 1 & 2, We get

x=0.4(Cost of per minute charge) & y=1.1(Cost Of Per Kilometre charge)

Now, Roy's ride took 10 minutes & The distance travelled was 15 km . Thus, the cost of Roy's Ride is 10x+15y ⇔ 10×0.4 + 15×1.1 ⇔ $20.5

Hence, the total cost of Roy's ride is 20.5 + 2.55(fixed cost) = $23.05
