15 because 6*3/2 is 9 9+6=15
Mixing is a physical reaction, which does not change any chemical properties of elements and molecules because it does not change the number of protons.
It is the number of protons that determine the unique properties of each element (hence why the periodic table sorts elements by increasing the number of protons).
Answer:
x = 8
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to the exterior angle that's supplementary to the third interior angle:
7x + 6 + 22 = 9x + 12 add like terms
7x + 28 = 9x + 12 export like terms to the same side of the equation
28 - 12 = 9x - 7x
16 = 2x divide both sides by 2
8 = x
Hi, a number line that goes up and down is called the y-axis. However, a number line that goes left and right is called the x-axis.
