1. 3x-17=x+3
2. 6+5x-1/3=10
3. 7+3-4x/5=0
4. 8+5x-2=-14
5. x+7=5x-9
6. (x+11/3)-5=1

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

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

df =

both have same length

answer is 1
