3) T = 8V
a) when V = 7, T would be = T = 8(7) = 56
b) when T = 24, V would be = 24 = 8V = V = 24/8 = 3
4) a) Equation would be: A = 4B
b) When B = 12, A would be = A = 4(12) = 48
c) When A = 13, B would be = 13 = 4B = B = 13/4
[Do all questions, with the same pattern and let me know, in case of doubt]
Hope this helps!
