Practice SHORT ANSWER
So, the problem you are given to solve here is:
You and a group of friends are going on a kayaking trip on a river. You
will travel 4 miles upstream against the current, take a break for half
an hour, and travel 4 miles downstream with the current. Your group's
average kayaking speed without a current is 2.4 miles per hour.
Your group decides to kayak on a river that has a current with a speed
of 0.8 mile per hour. Based on this information, how many hours will
your trip take, including the half an hour break?

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

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
