Answer:
Sam
Step-by-step explanation:
Patty: 325.75/8 = 40.72/hr
Quinn: 125.5/3 = 41.83/hr
Reece: 74.85/2 = 37.43/hr
Sam: 215.25/5 = 43.05/hr
2x + y = 10
5x - y = 18
7x = 28
x = 4
2(4) + y = 10
8 + y = 10
y = 2
(4,2)
Since <span><span>−64</span><span>-64</span></span> does not contain the variable to solve for, move it to the right side of the equation by adding <span>6464</span> to both sides.<span><span><span>x2</span>=64</span><span><span>x2</span>=64</span></span>Take the square root of both sides of the equation to eliminate the exponent on the left side.<span><span>x=<span>±<span>√64</span></span></span><span>x=<span>±64</span></span></span>The complete solution is the result of both the positive and negative portions of the solution.
<span>x=8,<span>−<span>8</span></span></span>
