Let white marbles = x
Purple marbles = 5x + 2
Given:
x + 5x + 2 = 104
6x = 102
x = 17
Purple marbles = 5(17) + 2 = 85 + 2 = 87
Answer:
see the attachment
Step-by-step explanation:
It is convenient to graph this equation using the x- and y-intercepts.
The x-intercept is found where y=0, so ...
4x = 36
x = 9
The y-intercept is found where x=0, so ...
-6y = 36
y = -6
<em>Graph the two points (9, 0) and (0, -6) and draw a line through them</em>. The graph is shown below.
The sum of the three angles of a triangle is always 180 degrees. If the triangle is right, which means one of the angles measures 90 degrees, the other two angles should add up to 90 degrees. With this condition and the given above, x + 15 + 2x = 90. Solving for x in the equation gives x = 25. Substituting x to the given expression for the acute angles gives the measurements of 40 and 50 degrees. Thus, the smallest angle of the triangle is <em>40 degrees</em>.
