Answer:
24
Step-by-step explanation:
(a/b)/(c/d) = (a*d)/(c*b)
(13/3) / (2/11) = (13*11)/(3*2) = 143/6 = 23.8333
the integer closest to 23.83333 is:
24
C/d + 2 = f/g (subtract 2 from each side)
c/d + 2 - 2 = f/g - 2
c/d = f/g - 2 (multiply d to each side)
c/d*d = d(f/g - 2)

See answers below
Step-by-step explanation:
Expand the brackets. 7 ( 5 + g ) 11 ( 3s – 4 ) 4 ( 4 – x ) 8 ( 6 + 4w )
We will expand each of the bracket using distributive property
For the expression 7(5+g)
7(5)+7g
= 35+7g
For the expression 11(3s-4)
= 11(3s)-11(4)
= 33s-44
For the expression 4(4-x)
= 4(4)-4x
= 16-4x
For the expression 8(6+4w)
= 8(6)+8(4w)
= 48+32w
