説明:
Solve the equation 2x − 5 = 7 to find the value of x.
説明:
Average Speed = Total Distance / Total Time.
説明:
Solve the equation x − 3 = 7 to find the value of x.
説明:
Use the formula Total = Mathematics + Physics − Both to find the number of students who study only Mathematics:
30 = 18 + 15 − 12
説明:
Probability = (Number of favorable outcomes) / (Total number of outcomes).
説明:
Average Speed = Total Distance / Total Time.
説明:
Let the smaller even integer be x. Then the next consecutive even integer is x + 2. Use the equation x (x+2) = 288 to find x.
説明:
Solve the equation 3x + 4 = 16 to find the value of x.
説明:
Use the Pythagorean theorem to find the length of the diagonal of a square.
説明:
Solve the given system of equations to find the value of a.
