Question

It's urgent. Plz help

Answer 1

1. 9C+160=5F
9C=5F-160
C=(5F-160)/9

2.9C+160=5F
5F=9C+160
F=(9C+160)/5

3. I=PTR/100
PTR=I×100
P=I×100/TR

4.v^2=u^2+2aS
2aS=v^2-u^2
S=(v^2-u^2)/2a

5.s=ut+1/2 at^2
1/2 at^2=s-ut
at^2=2(s-ut)
a=2(s-ut)/t^2

6.s=n/2 (a+l)
a+l=2s/n
l=2s/n -a

7.l=a+(n-1)d
l-a=(n-1)d
(l-a)/d=n-1
(l-a)/d + 1=n
n=(l-a+d)/d


HOPE IT HELPS!!
