To convert 2.7 hours into seconds, which two ratios could you multiply by?

2.7 hrs x 60 (for minutes) = amount of minutes
amount of minutes x 60 (for seconds) = amount of seconds.

IN this case

2.7 x 60 = 162 minutes

162 x 60 = 9720 seconds.

so the two rations are 1:60 or (hr: min) then 1:60 or (min: seconds)

hope this helps :D

Simplifying 14x + -50 = 16x + -49 + -2x + -1 reorder the terms: -50 + 14x = 16x + -49 + -2x + -1 reorder the terms: -50 + 14x = -49 + -1 + 16x + -2x combine like terms: -49 + -1 = -50 -50 + 14x = -50 + 16x + -2x combine like terms: 16x + -2x = 14x -50 + 14x = -50 + 14x add '50' to each side of the equation. -50 + 50 + 14x = -50 + 50 + 14x combine like terms: -50 + 50 = 0 0 + 14x = -50 + 50 + 14x 14x = -50 + 50 + 14x combine like terms: -50 + 50 = 0 14x = 0 + 14x 14x = 14x add '-14x' to each side of the equation. 14x + -14x = 14x + -14x combine like terms: 14x + -14x = 0 0 = 14x + -14x combine like terms: 14x + -14x = 0 0 = 0 solving 0 = 0 couldn't find a variable to solve for. this equation is an identity, all real numbers are solutions. good luck hope i : )
