Write an equation for the hanger diagram and then us the sketch to show how to solve the equation algebraically.
1 answer:
Step-by-step explanation:
Since there are 3 w's and a 1 on one side and 7 1's on the other and the hanger diagram shows they are even, we can set them equal to each other.
3w + 1 = 7 <em>Subtract</em><em> </em><em>1</em><em> </em><em>from both</em><em> </em><em>sides</em>
3w = 6 <em>Divide</em><em> </em><em>3</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>
w = 2
