1/2 n + 10.5 =3.5 find the value of n

n= -14

Step-by-step explanation:

First, convert into a decimal:

as a decimal is 0.5

now the equation is 0.5n+10.5=3.5

Move the constant to the right and change its sign:

0.5n=3.5-10.5

Calculate the difference:

0.5n=3.5-10.5

0.5n= -7

Divide both sides of the equation by 0.5:

0.5n÷0.5= -7÷0.5

n= -14

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
