Astronomers measure large distances in light-years. one light-yearis the distance that light can travel in one year, or approximately 5.88x10^12 miles. suppose a star is 2.23x10^2 light-years from earth. in scientific notation, approximately how many miles is it? a) 2.23x10^14 b) 1.31x10^14 c) 1.31x10^15 d) 5.88x10^12

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

after simplifying it i got: -36.25 as my answer. hope that !
