Let m = miles
let c = cost
Create a system of equations.
taxi company 1: c = $1.20m + $2
taxi company 2 c = $1.40m + $1
Set both equations equal to each other to solve for variable m.
$1.20m + $2 = $1.40m + $1
Subtract $1.20 from both sides and Subtract $1 from both sides.
$1 = $0.20m.
Divide each side by $0.20.
5 = m.
Plug 5 into one of our original equations for m.
c = $1.20(5) + $2.
Simplify the right side of the equation
c = $8
In conclusion, c = $8 and m = 5
Answer:
<u>4</u>( -1 <u>-11 </u>)+2 (<u>17</u>)
<u>-14</u>
Step-by-step explanation:
This one requires more abstract thinking than you'd expect!
So essentially you want to count up how many -11's there are, -1's and 17's.
There are four -11's and four -1's, and two 17's.
So that means 4 x -11 + 4x-1 + 2x17 = The Total Sum of Subscribers
We can "factor out" a 4 from the -11 and -1.
4( -1 - 11) + 2(17)
So then you'd solve that and get
<u>-14</u>
