Ms. gallegos works 8 hours per day. she made $2,400 for working 10 days. how much money does ms. gallegos make per hour?

First, calculate the number of working hours in 10 days:

8 hours × 10 days = 80 hours

We can now rephrase the original statement to say "Ms. Gallegos made $2,400 for working 80 hours." Use this information to create the following equation:

80w = 2,400

Divide both sides by 80:

w = 30

Ms. Gallegos' hourly wage is $30

I hope this helps!

79

Step-by-step explanation:

Given the expression

x + 1/x = 9

Square both sides

(x + 1/x)^2 = 9^2

x^2 + 2x(1/x)+ (1/x)^2 = 81

x^2 + 2 + 1/x^2 = 81

x^2+1/x^2+2 = 81

x^2+1/x^2 = 81-2

x^2+1/x^2+ = 79

Hence the value of x^2+1/x^2 is 79
