Marco requires $420 to purchase a new smartphone along with accessories. The equation 75-495=420 demonstrates this while adding $75 to $420 yields a total of $495.
To plot the graph of a linear equation, two points suffice to create a line.
Nevertheless, errors can occur; thus, when the line is drawn, it may seem accurate. Two points will always define a line, regardless of the correctness of those points.
To confirm that the points are accurate, we find a third point to verify that the two previously calculated points are correct and that all points align on the same line. If they don’t, an error has been made.
Option A) is the correct choice
Wallet = belt + 31
jacket = 3 · belt
176 = belt + wallet + jacket
176 = belt + (belt + 31) + (3 · belt)
176 = (2 · belt) + 31 + (3 · belt)
176 = (5 · belt) + 31
5 ·belt = 145
belt = 29

Answer:
The speed is 2 1/2 miles per hour.
Step-by-step explanation:
To determine the rate, divide the distance by the time taken.
5/8 mile ÷ 1/4 hour
Applying the copy dot flip method:
5/8 * 4/1
Gives us 5/2 miles per hour.
Which simplifies to 2 1/2 miles per hour.
