A sectore with a radius of 15cm has a centeral angle measure of 8pi/5 (in radians)

i think the answer is d im not sure

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
