The solution of the equation is  x=\frac{11}{7}

Step-by-step explanation:

To simplify an equation of x

  • Simplify each side of the equation
  • Collect x in side and the numerical terms in the other side
  • Find the value of x

∵ The equation is 2x + \frac{1-x}{4}=3

- Multiply all terms of the equation by 4 to cancel the denominator

 of the 2nd term in the left hand side

∵ The equation is 4(2x) +4 (\frac{1-x}{4})=4(3)

∴ 8x + (1 - x) = 12

∴ 8x + 1 - x = 12

- Add like terms

∴ (8x - x) + 1 = 12

∴ 7x + 1 = 12

- Subtract 1 from both sides

∴ 7x = 11

- Divide both sides by 7

∴ x=\frac{11}{7}

The solution of the equation is  x=\frac{11}{7}

An airplane is flying 600 mph on a horizontal path that will take it directly over an observer. The airplane remains a constant
dezoksy [38]
<h2>Change of the distance between the observer and the airplane when X = 5 miles is 348.84 mph</h2>

Step-by-step explanation:

We have by Pythagoras theorem

       Distance between the observer and the airplane² = Horizontal distance² + Altitude²

        d² = h² + a²

Here we have

          h = X = 5 miles

          a = 7 miles

          d² = 5² + 7²  = 74

          d =8.60 miles

          \frac{dh}{dt}=600mph\\\\\frac{da}{dt}=0

Differentiating d² = h² + a² with respect to time

            2d\frac{dd}{dt}=2h\frac{dh}{dt}+2a\frac{da}{dt}\\\\8.60\frac{dd}{dt}=5\times 600+7\times 0\\\\\frac{dd}{dt}=348.84mph

Change of the distance between the observer and the airplane when X = 5 miles is 348.84 mph
