If you would like to find the rate of the bicycle and the scooter, you can do this using the following steps:

a scooter: 18 miles ... 2 * r + 5 mph
a bicycle: 8 miles ... r = ? 

18 * r = 8 * (2 * r + 5)
18 * r = 16 * r + 40
18 * r - 16 * r = 40
2 * r = 40
r = 20 mph

a bicycle: r = 20 mph
a scooter: 2 * r + 5 mph = 2 * 20 + 5 = 45 mph

The correct result would be: The rate of the scooter is 45 mph and the rate of the bicycle is 20 mph.

Answer:

  (a)  (6, 2)

Step-by-step explanation:

The system of equations has one of them in y= form, so it lends itself to solution by substitution.

__

Using the equation for y to substitute into the first equation, we have ...

  2x -y = 10

  2x -(-1/2x +5) = 10 . . . . . substitute for y

  2x +1/2x -5 = 10 . . . . . eliminate parentheses

  5/2x = 15 . . . . . . . . . add 5, collect terms

  x = 6 . . . . . . . . . . . multiply by 2/5

Using the equation for y, we have ...

  y = -1/2(6) +5 = -3 +5

  y = 2

The solution is (x, y) = (6, 2).

Find X<br><br> Options:<br><br> 6<br> 4 square root 6<br> 6<br> square root 146
elena-14-01-66 [18.8K]

For this case we can apply the Pythagorean theorem to find "x". Taking the rectangle triangle of base 5 we have:

x = \sqrt {11 ^ 2-5 ^ 2}\\x = \sqrt {121-25}\\x = \sqrt {96}\\\x = \sqrt {4 ^ 2 * 6}

By definition of power properties we have:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

So:

x = 4 \sqrt {6}

Answer:

x = 4 \sqrt {6}

I am stuck on this question it was can you add 4+2x to get 6x
Fed [463]

Answer:

No you can't.

Step-by-step explanation:

4 is an integer, and 2x isn't so you can't add them together. If 4 was 4x or 2x was 2, then you'd get 6, but you can't add them. Hope this helps :)
