Solve the system:
10r-4t=6
7r +5t=12

t=1

r=1

Step-by-step explanation:

10r-4t=6   equation 1

7r +5t=12   equation 2

using equation 1 we have:

10r-4t=6  

10r = 6+4t

r= (6+4t)/10  equation 3

using equation 3 in equation 2 we have:

7((6+4t)/10)) +5t=12

4.2 + 2.8t  +5t =12

7.8t = 12-4.2

7.8t= 7.8

t = 7.8/7.8

t=1

so we have:

r= (6+4(1))/10

r= 10/10

r=1

the answer is. -82562234434584

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
