Solve each inequality (question 20 please, already have 14 and 17 figured out)

r-ruslan [8.4K]

Answer:

$y>\frac{8}{3}$

Step-by-step explanation:

$\frac{3y-4}{0.2}-8>12\\\frac{3y-4}{0.2} > 20\\5(3y-4)>20\\3y-4>4\\3y>8\\y>\frac{8}{3}$

Dividing by 0.2 is the same as multiplying by 5. Check your calculator if you don't believe me.
