5(41  - x) +  -7(y + x)      x = -2 and y  = -4

 

5 ( 41 - - 2)  +  -7 ( -2 + -4)  =

 

5 (43)  +   - 7 (-6)  =

 

215  + 42   =  

 

257

 

 

(4)7/8 + 7(5/12 + 1/8) - 10    =                     get a common denominator of 24 within the parentheses

 

28/8   + 7 ( 10/24 + 3/24)  - 10  =

 

7/2  + 7 ( 13 / 24)  - 10  =

 

7 / 2  +   91 / 24    - 10  =                    common denominator  = 24

 

84 / 24  +   91 / 24  -  240 / 24  =

 

175 / 24  -  240 / 24  =

 

-65 / 24  

 

 

 

 

Jenny has six basketball teams, each team needs new shoes for an upcoming tournament, and she spent 630 dollars on all the shoes thus far. Each pair of shoes cost 6 times more than last year’s pairs of shoes.

How much did last year’s shoes cost?

 

 

Last year's shoes must have 1/6 the cost of this year's....so   ...     (1/6) * (630)  =   [600 + 30] / 6 =

 

600/ 6  +  30 / 6    =

 

100 +  5  =

 

$105
