Joe earns $425 a week for working 40 hours and an additional $20 an hour for each hour over 40. Last week, Joe made $485. Write
Tasya [4]

Answer:

Joe worked 3 hours overtime.

Step-by-step explanation:

Let t = number of hours overworked

425 + 20 × t = 485

425 + 20t = 485

20t = 485 - 425

     = 60

\frac{20t}{20} = \frac{60}{20}

t = 3

\therefore Joe worked 3 hours over time.

Hope this helps :)

X^2+_x+_=0<br> Please help need to pass this class
snow_tiger [21]
Answer:
x^2+0x+(-x^2)=0

Explanation:
x^2+0x+(-x^2)=0
Anything multiplied by 0 is equal to 0
x^2+0+(-x^2)=0
x^2+(-x^2)=0
A positive and a negative makes a negative
x^2-x^2=0
0=0

For these types of problems, play around with multiplying by 0 and adding negatives.

I hope this helps! Please comment if you have any questions.

Francisco and Ryan are stuck simplifying radical expressions. Francisco has simplified to the quantity of x to the one half powe
Wewaii [24]
X to the one half power, over x to the three eighteenth power is equal to x to the one half power, divided by x to the one sixth power, which equals x to the power of (one half minus one sixth), or x to the one third power. 

<span>The twenty seventh root of the quantity of x to the second times x to the third times x to the fourth equals the twenty seventh root of x to the ninth power which equals x to the one third power. </span>

<span>I cannot say whether Francisco and Ryan started with equivalent expressions but on final simplification they ended up the same. One might reasonably assume they started with equivalent expressions, but who knows if they made any mistakes in their simplifications.</span>
