The problem is 3+6x = 15 with x being the number of white numbers.
Isolate variable by subtracting 3 on both sides: 6x = 12.
Isolate variable by dividing 6 on both sides: x = 2
The number of white marbles is 2.
Anything without a variable in front.
In other words, the constants are -3.7 and 1/3
Asa. the side is in the middle of the angles
Using supplementary angles, it is found that the measure of angle x is of 65º.
<h3>What are supplementary angles?</h3>
Angles are called supplementary if the sum of their measures is of 180º.
In this problem, angles x, 25, and 90º are supplementary, hence:
x + 25 + 90 = 180
x = 180 - (25 + 90)
x = 65º.
The measure of angle x is of 65º.
