Robert has scored an 88, 92, 83, 79, and 87 on his last five rounds of golf. What must he shoot on this sixth round to have a mean of 85?

Step-by-step explanation:

Robert has scored:

88+92+83+79+87+x=(85*6)

429+x=510

x=510-429=81

he needs to score an 81

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

: )

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
