19 tens are in 192 if you multiply 19 by 10 you will get 190 so the answer is 192 hope this helped brainly plz if correct
you just do 144 divided by 8. There are 18 members of the class.
(((1/y - 1) + (5/12)) = (-2/3y - 3))
((((1)(12)/12(y - 1) + (5(y + 1)/12(y + 1) = (-2/3y - 3))
((12/12y - 12) + (5y + 5/12y - 12)) = (-2/3y - 3))
((5y + 17/12y - 12) = (-2/3y - 3)
(12y - 12/5 + 17) × (5y + 17/12y - 12) = (-2/3y - 3)(12y - 2/5 + 17)
y = -21y + 4/66y - 66
y = -7/22 - 2/33
y = -25/66
let
y = k/x
where k is proportional constant
putting y = 37 and x =72
37 = k / 72
k = 37 × 72
so now we got value of k
.put it again in equation
y = 37×72/x
let's calculate y when x = 12
y = 37 × 72/12 = 37 × 6 = 222
