Let the speed of the current equal c
and the speed of the boat in still water equal b.

b + c = 1.5 (b - c)
b + c = 1.5b - 1.5c
0.5b = 2.5c
b = 5c

The speed of the current is 1.5 mph so
b = 5 * 1.5 = 7.5 mph

Expand and simplify 3(x+2)+2(x-1)
lilavasa [31]
If you would like to expand and simplify 3 * (x + 2) + 2 * (x - 1), you can do this using the following steps:

3 * (x + 2) + 2 * (x - 1) = 3 * x + 3 * 2 + 2 * x - 2 * 1 = 5 * x + 6 - 2 = 5 * x + 4

The correct result would be 5 * x + 4.

3(12x – 9) + 9 = 2x + 4<br> Would this be infinite solution, one solution or no solution?
timama [110]

Answer:

One solution

Step-by-step explanation:

Let us first <u>expand</u> the left side of the equation to rid of the parenthesis:

3*12x-3*9+9=2x+4\\36x-27+9=2x+4\\36x-18=2x+4

Now let us <u>isolate</u> the variable to sove for x:

36x-2x=4+18\\34x=22\\x=\frac{22}{34}\\x=\frac{11}{17}

Therefore, x=\frac{11}{17}. As you can see, there is just one solution.

sdas [7]

Answer:

<h2>25.96%</h2>

Step-by-step explanation:

Givens

  • The old record is 6.75 meters.
  • The new record is 8.5 meters.

If 6.75 meters represents 100%, which percentage would represents 8.5 meters? (we use the rule of three).

8.5 \times \frac{100 \%}{6.75 } =125.93 \%

Then, we subtract 125.96% - 100% = 25.96%

Therefore, the percentage between the two records is 25.96%
