Question

Can someone help me with the ones that aren’t done

Answer 1

5:

C = 5/9(F - 32)

C = 5/9(F) - 17.777

-5/9(F) + C = -17.777

-5/9(F) = -C - 17.777

F = 5/9(C) + 32.0306

Answer 2

`5.\, F=(9C)/(5)+32\\6.\,y=(c-ax)/(b)\\7.\,p=(mq)/(n)\\8.\,t=(A-P)/(Pr)\\9.\,y=(12-6x)/(5)\\10.\,y=(9x-6)/(3)\\12. x=(9+5y)/(6)\\13.\,\pi=(c)/(d)\\14.\,A=(s^2)/(R)\\15.\,w=(P-2l)/(2)\\16.\,y=(3x-2)/(5)\\17.,x=(6-3by)/(2a)\\18.\,w=(V)/(lh)`

Explanation:

We need to solve following equations in terms of indicated variable:

`5.C=(5)/(9)\left ( F-32 \right ):F\\6.ax+by=c;y\\7.(m)/(n)=(p)/(q);p\\8.A=P+Prt;t\\9.6x+5y=12;y\\10.3y+2=9x-4;y\\12.6x-5y=9;x\\13.C=\pi d\\14.R=(s^2)/(A);A\\15.P=2l+2w;w\\16.3x-5y=2;y\\17.2ax+3by=6;x\\18.V=lwh;w`

Solution:

`5.\, F=(9C)/(5)+32\\6.\,y=(c-ax)/(b)\\7.\,p=(mq)/(n)\\8.\,t=(A-P)/(Pr)\\9.\,y=(12-6x)/(5)\\10.\,y=(9x-6)/(3)\\12. x=(9+5y)/(6)\\13.\,\pi=(c)/(d)\\14.\,A=(s^2)/(R)\\15.\,w=(P-2l)/(2)\\16.\,y=(3x-2)/(5)\\17.,x=(6-3by)/(2a)\\18.\,w=(V)/(lh)`
