Here is the equation:

⇒

You need to get "x" by itself so minus 3 from each side

⇒

⇒

Divide 8 by 2

÷

x=4
So each 4 is equivalent to 4
Lets check:

⇒

⇒

So that means that Marcus practiced the piano for 4 hours and Donnel practiced for 7
<h3>Answer:</h3><h3>The equation for the slope of a line, given two coordinate points, (x1,y1) , (x2,y2), is (y2-y1)/(x2-x1) </h3><h3> So we get slope = (1-(-5)) / (4-1) = 6/3 = 2</h3><h3>A is your correct answer.</h3>
Hope this helps! please consider marking my answer the brainliest :)
I dont think the answer is always. Because integers are always whole numbers. Hope that helps a little?
10 faces. 2:8 x:40 so 40÷8= 5 so x: 5x2 whixh is 10
