Answer:
w = 5
Step-by-step explanation:
Combining like terms is a very important part to this equation!
<em>5.2w - 1.4 = 3.2w + 8.6</em>
<em>I added 1.4 to the right side first, though you must do it to the left side of the equation as well</em>
<em>5.2w - 1.4 + (1.4) = 3.2w + 8.6 + (1.4)</em>
<em>5.2w = 3.2w + 10</em>
<em>Combine the remaining like terms. I subtracted 3.2w from both sides. </em>
<em>5.2w + (-3.2w) = 3.2w + (-3.2) +10</em>
<em>2w = 10</em>
<em>Now divide</em>
<em>2w = 10</em>
<em>w = </em><em />
<em>w = 5</em>

If angle 2 and 1 are congruent then angle 2 should be 110° and other measures should be 70°
<span>The value of y when x=3 when the value of y varies directly with x^2, and y = 150 when x = 5 is 54. Since the value of y varies directly with x2, then: y = k * x^2, where k is constant. When y = 150 and x = 5, the value of constant is: 150 = k * 5^2. 150 = k * 25. k = 150/25. k = 6. Thus, when x = 3, the value of y will be: y = 6 * 3^2. y = 6 * 9. y = 54.</span>
