To solve the equation 3x - 1/2 = 3.5 × 2, let's first simplify the right side: 3.5 × 2 = 7 Now the equation becomes: 3x - 1/2 = 7 To isolate x, let's add 1/2 to both sides of the equation: 3x - 1/2 + 1/2 = 7 + 1/2 This simplifies to: 3x = 7 + 1/2 To add 7 and 1/2, we need to find a common denominator, which is 2: 7 + 1/2 = 14/2 + 1/2 = 15/2 Now the equation becomes: 3x = 15/2 To solve for x, divide both sides of the equation by 3: (3x)/3 = (15/2)/3 This simplifies to: x = 15/6 To simplify the fraction 15/6, we can divide the numerator and denominator by their greatest common divisor, which is 3: x = (15/3)/(6/3) = 5/2 Therefore, the solution to the equation 3x - 1/2 = 3.5 × 2 is x = 5/2.

"""13.已知角A为ABC的内角, cosA=-4/5 ,则sin2A=()？"""
根据三角恒等式，有sin^2(A) + cos^2(A) = 1。所以sin^2(A) = 1 - cos^2(A) = 1 - (-4/5)^2 = 1 - 16/25 = 9/25。然后利用sin(2A) = 2sin(A)cos(A)，得到sin(2A) = 2sin(A)cos(A) = 2 * (√(9/25)) * (-4/5) = -8/5。所以sin2A = -8/5。
