Question

Create an equivalent expressions for each of the following.

-6 ( 10x-4)

(-y+5.3)+ (7.2y -9)

5-8(4-1v +3v)

-10 ( 3+ 10v) -9v

( 30/45G + 20) - ( 8/9G + 7)

Answer 1

-6 ( 10x-4) Use the distributive law:-

= -60x + 24

(-y+5.3)+ (7.2y -9) First remove parentheses:-

= -y + 5.3 + 7.2y - 9 Now add like terms:-

= 7.2y - y -9 + 5.3

= 6.2y - 3.7

5-8(4-1v +3v)

= 5 - 32+ 8v - 24v

= -27 - 16v

-10 ( 3+ 10v) -9v

= -30 - 100v - 9v

= -30 - 109v

30/45G + 20) - ( 8/9G + 7) Converting:- 8/9G = 40/45G :-

= 30/45G - 40/45G + 20 - 7

= -10/45G + 13

= -2/9G + 13
