Use PEMDAS
5.8z+7<30.2
-7 -7
5.8z < 23.2
divide 5.8 on both sides
z<4
4(1.5z+1.25) less than or equal to -7
6z+ 5 is less than or equal to -7
-5 -5 (subtract 5 on both sides)
6z is less than or equal to -12
Divide both sides by 6 to isolate z
Z is less than or equal to -2
That means the first equation is the answer as the second equation’s greatest value is -2 which is less than 1
Wait LOL I just realized u posted a month ago
Wait I fucked up it was greater than or equal to for the second inequality so it’s z is greater than or equal to -2 which means both equations work
I'm sorry should've deleted it or something
Yeah I wrote this. Comment on a bunch of other ones too so I got the help I needed.Thanks for the help tho
Lol, I was also about to reply and saw that it was so long ago
Sorry for bothering anyone but by now I’m just that desperate okay
Solve each of the given inequalities for z. Which of the inequalities have 1 as a solution?
Inequality 1: 2(2.9z+3.5)<30.2
Inequality 2: 4(1.5z+1.25)_>-7.0
Also the teacher wants me to show my work
