Step-by-step explanation:
Ratio of number of classes and the time taken to conduct each one of them on Thursday = 6 : 8
Ratio of number of classes and the time taken to conduct each one of them on Friday = c : 4
Which means :-
6 : 8 :: c : 4
6/8 = c/4
= 6 × 4 = c × 8
= 24 = 3 × 8
c = 3
The ratio = 6 : 8 :: 3 : 4
Which means that C = 3 .

Answer:
a) z=5w-3
we have w, so we multiply it by 5 to make it 5w
and then we subtract 3 to make it 5w-3
w⇒ ×5 ⇒ -3 ⇒ z
b) x⇒ +2 = x+2
Now × 7 makes it 7(x+2)
so y=7(x+2)
