4/15x + 5/6x + 1/2 = 1 3/5

x = 1

Step-by-step explanation:

Given

x + x + = 1 ← convert to an improper fraction

x + x + =

Multiply through by 30 ( the LCM of 15, 6, 2, 5 ) to clear the fractions

8x + 25x + 15 = 48

33x + 15 = 48 ( subtract 15 from both sides )

33x = 33 ( divide both sides by 33 )

x = 1

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
