Question

check if p is 5 is solution of 1 by 2 (p+ 4) is 5.4​

Answer 1

P=5

subistuting the value of P in the equation

1/2(p+4)=5.4

1/2(5+4)=5.4

1/18=5.4

0.0555=5.4

since p=5 is not the correct value for this equation

the correct value of the equation is

1/2(p+4)=5.4

1=5.4×(2p+8)

1=1.08p+43.2

1-43.2=1.08p

-42.2=1.08p

-42.2/1.08=p

-39.07=p
