Let s be the speed of the boat in still water.
Let c be the speed of the current.
s - c = 48/6 = 8
s + c = 48/4 = 12
Adding the two equations, we get:
2s = 20
s = 10
The answer is 10 miles per hour.
The correct answer is 3x+90=180
<em>Because you add the 2x and the x and you get 3x then there is a 90 degree angles so you add that and =180</em>
<em>Once you put it in the equation you can subtract 90 from 180 and you get 90 which you then divided by 3x and x equals 30</em>

Answer:
Step-by-step explanation:
<u><em>The question is</em></u>
Find the measure of angle x
we know that
In this problem
----> by alternate interior angles
Because, each pair of these angles are inside the parallel lines, and on opposite sides of the transversal.
I am not sure what does that question mean by simplify. If it means not to solve and just arrange;
You can divide the whole of the equation to m^2
Then you get;
19/m -4 +4
And you can divide the whole equation to 4 then you get;
19/4m -1 +1
You can also write as ;
(1/m * 19/4) - 1 + 1
Answer:
The 3rd term would be the parenthesis to the 7th power.
