Answer:

x = \frac{3+\sqrt{105} }{8}  , \frac{3-\sqrt{105} }{8}  x=1.655,-0.905

Step-by-step explanation:

3x+6 = 4x^2

4x^2 -3x -6 = 0

x = \frac{3+\sqrt{105} }{8}  , \frac{3-\sqrt{105} }{8}  x=1.655,-0.905

John is 1 8 meter shorter than Paul, and Paul is 0.25 meter taller than Andrew. If John’s height is 1 3 4 meters, what is Andrew
9966 [12]

<u><em>Answer:</em></u>

Andrew's height is 1\frac{5}{8} meters

<em><u>Explanation:</u></em>

We know that John's height is 1\frac{3}{4} meters

<u>We are given that:</u>

John is \frac{1}{8} meters shorter than Paul

<u>This means that:</u>

Paul's height = John's height + \frac{1}{8}

Paul's height = 1\frac{3}{4} + \frac{1}{8} = 1\frac{7}{8} meter

<u>We are given that:</u>

Paul is 0.25 meters taller than Andrew

<u>This means that:</u>

Andrew's height = Paul's height - 0.25

Andrew's height = 1\frac{7}{8} - 0.25 = 1\frac{5}{8} meters

Hope this helps :)

Andreas93 [3]

Answer:

We know that 30/25 is 1.2 or 1 1/5. SO if we divide 20 by that then we'll get 16.6667. So I won't give you the answer because its best that you learn to do this yourself because its more beneficial than telling you. What you have left is 16.6667=4x-4. Combine like terms and you'll get your answer. But if your still stuck then you can just let me know and I'll help you as much as I can.
