Okay so my math teacher just sits at her desk all day can someone help me with this review for my final pls...

Perform the indicated operations and simplify:
-4/5(-15/16)
-3(x-4)-4(5x-1)

Respuesta :

apologiabiology
remember
(a/b)(c/d)=(ac)/(bd)
just multiply tp and bottom

and
(-)(-)=(+)
(+)(+)=(+)
(+)(-)=(-)
(-)(+)=(-)

and distributive property
a(b+c)=ab+ac

so


-4/5(-15/16)=(-4*-15)/(5*16)=(60)/(80)=6/8=3/4


-3(x-4)-4(5x-1)=
-3(x)-3(-4)-4(5x)-4(-1)=
-3x+12-20x+4=
-3x-20x+12+4=
-23x+16
