Answer:
2 wings/dollar
Step-by-step explanation:
The unit cost is $4 / 8 wings, or $0.50/wing. This is equivalent to 2 wings/dollar.
The "e" just lets you know that it's scientific notation.
He rode his bike 45 minutes each day:
45x6 = 270 total time cycled
Jogging time = total workout time - cycle time/6
360-270= 90/6= 15 minutes jogged each day
Answer:
The system of equations has a one unique solution
Step-by-step explanation:
To quickly determine the number of solutions of a linear system of equations, we need to express each of the equations in slope-intercept form, so we can compare their slopes, and decide:
1) if they intersect at a unique point (when the slopes are different) thus giving a one solution, or
2) if the slopes have the exact same value giving parallel lines (with no intersections, and the y-intercept is different so there is no solution), or
3) if there is an infinite number of solutions (both lines are exactly the same, that is same slope and same y-intercept)
So we write them in slope -intercept form:
First equation:

second equation:

So we see that their slopes are different (for the first one slope = -6, and for the second one slope= -3/2) and then the lines must intercept in a one unique point. Therefore the system of equations has a one unique solution.
