For each story, write an equation that describes the relationship between the two quantities. Diego collected x kg of recycling. Lin collected 2/5 more than that.

Lin biked x km. Diego biked 3/10 less than that.

Diego read for x minutes. Lin read 4/7 of that.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
