9(2k+3)+2=11(k-y) help please and fast and show work, ty! Btw I’m being timed please help..

mel-nik [20]

9(2k+3)+2=11(k-y)
18k + 27 + 2 = 11k - 11y
18k + 29 = 11k - 11y
18k - 11k + 29 = 11k - 11y - 11k
7k + 29 = -11y
7k + 29 - 29 = -11y - 29
7k = -11y - 29
7k / 7 = -11/7y - 29/7
K = -11/7y - 29/7

Trevor is swimming laps to raise money for the local food bank. He earns $1.85 per lap and has already swum 23 laps.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

The inequality is 1.85x - 42.55 > 100. 42.55 is the amount already raised, 1.85x is number of laps times the money raised by them.
