Question

if X equal to root 7 upon 5 and 5 upon x is equal to P root7​

Answer 1

$\large\blue{\textsf{✩ Answer ✓ }}$

p=(25/7)

x= sqrt(7)/5

substitute into second equation.

{5/(sqrt 7/5)}=p sqrt (7)

invert and multiply

(25/sqrt (7))=p (sqrt (7))

multiply both sides by sqrt (7)

25 =7p

divide by 7

(25/7)=p

Check

sqrt (7)=2.65

x=2.65/5, or 0.53

5/0.53 is 9.45

(25/7)*2.65=9.46

This is the same given that sqrt (7) is being rounded.
