Answer:
Step-by-step explanation:
x= money earned per hour working as a cashier.
y=money earned per hour working delivering newspapers.
We propose the following system of equations:
5x + 4y =77
6x + 3y=78
We solve the system by reduction method:
-6*(5x+4y=77) ⇒ -30x-24y=-462
5*(6x+3y=78)⇒ 30x+15y=390
---------------------------
-9y=-72 ⇒ y=-72 /-9=8
Now, we get the value of "x" replacing the value of "y" by "8" in any part of the equation above.
5x + 4(8)=77
5x+32=77
5x=77-32
5x=45
x=45/5=9
therefore;
money earned per hour working as a cashier= $9/ hour
money earned per hour working delivering newspapers=$8/hour
The correct answer for this question is this one: "The square root of terms separated by addition and subtraction cannot be calculated individually."
<span>The statement that best explains why the expression cannot be rewritten as during the next step is that t</span>he square root of terms separated by addition and subtraction cannot be calculated individually.
Hope this helps answer your question and have a nice day ahead. ..... hope that helps
