Answer:
See explaination
Step-by-step explanation:
To convert a second-order differential equation into a system of linear differential equation, we have to write y'' as x', for some variable x.
please kindly see attachment for the step by step solution of the given problem.
You would use the “is/of” method.
93 / 100 = x / 76
Cross multiply and divide:
7068 / 100 = 70.68
This means Pedro got around 70 to 71 questions correct and 5 or 6 questions incorrect.
10 - 2x = -5x -5
+2x +2x
10 = -3x -5
+5 +5
15= -3x
X= -5
If 1 inch is 13.5 feet, then 5 inches = (13.5 * 5) = 67.5 ft
