MArishka [77]

Answer:

h = 33 hours

Step-by-step explanation:

Given that,

Addison worked 6 more hours this week than last week. In total, she worked 72 hours this week and last week.

The equation is :

We need to find the number of hours

2h = 72 - 6

2h = 66

h = 33

Hence, Adison worked for 33 hours last week.

What does it mean when a question number is circled in a textbook
RoseWind [281]
This is only my opinion.  I could be wrong.

My guess is:

Somebody else used that book before you, maybe last year or
the year before, and it was somebody who didn't mind writing
in his book.

One day he didn't have time to write down the homework in his
assignment notebook, so he just circled the homework problems
in his textbook.

What is Y=2x-1 and Y=3x+2
Readme [11.4K]

Answer:

{y,x} = {-7,-3}

Step-by-step explanation:

- 3x = 2

  y - 2x = -1

-3x + y = 2        -2x + y = -1  

y = 2x - 1

(2x-1) - 3x = 2

    - x = 3   x = - 3

y = 2x-1

   x = -3

y = 2(-3)-1 = -7
