The number is 4.5

4.5

Step-by-step explanation:

let the number be x , then

10x + 15 = 60 ( subtract 15 from both sides )

10x = 45 ( divide both sides by 10 )

x = 4.5

The number is 4.5

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
