Step-by-step explanation:
1 m = 100 cm
Multiply:
100 * 400 = 40000
So she ran 40,000 centimeters.
Answer:
infinite solutions
Step-by-step explanation:
y=5/2x+2
2y= 5x +4
Multiply the first equation by 2
y = 5/2 x +2
2y = 5/2 *2 x +2 *2
2y = 5x +4
Since this is identical to the second equation (they are the same), the system of equations has infinite solutions
