We know that 1 gram = 100 centigrams.

We are given that Paul used 1 gram of salt for a chemistry experiment.

But since  1 gram = 100 centigrams.

That means Paul used 100 centigrams of salt for a chemistry experiment.

Hence, the correct answer is  Paul used 100 centigrams of salt for a chemistry experiment.

(x+30)+(x-30)=180

2x=180

x=90

x+30=y+20

90+30=y+20

y=100°

There for z = -10
