1200+0.0005x=1500+0.0015x

Mathematics
1 answer:
Daniel [21]3 years ago
4 0

Answer:

X=-300000

Step-by-step explanation:

Move variable to the left-hand side

1200+0.005x-0.0015x=1500

Move the constant to the right-hand side and change sign

0.005x-0.0015x=1500-1200

Combine like terms

-0.001x=1500-1200

Subtract the numbers

-0.001x=300

Divide both sides of the equation by -0.001

X=-300000

The LCD here is 4.  Convert 3(1 1/2 hrs) to 3(1 2/4 hrs), so that we now have:

3(1 2/4 hrs)  = 3 6/4 hrs

+2(1 1/4 hrs)  =  2 2/4 hrs

+2(3/4 hrs)   =       6/4 hrs

-------------------------------------

                          5 14/4 hrs, or

                          5 + 3 2/4 hrs, or

                              8 1/2 hours/week
