What is the solution of 5a + 12 < 2 and 5a - 12 < 3?
@jim_thompson5910
solve 5a + 12 < 2 for 'a' first
I got a<-2
good
solve 5a - 12 < 3 for 'a' next
is that the whole answer:)
no you need to solve 5a - 12 < 3 for 'a' now
This is what it look like and I can only choose one answer: What is the solution of 5a + 12 < 2 and 5a - 12 < 3? A. a<3 B. a<2 C. a<-2\ D. a>-2 and btw for the second one I got A<3
so the inequalities solve to a < -2 and a < 3 combine the two to get a < -2
so it's C
so i bring thos two answers together like this: a<-2 and a<3 and I get my answer?
a < -2 and a < 3 combine to a < -2 think about it: if a is some number less than -2 AND less than 3, then it's just less than -2
oh alright so my whole answer is c then right?
yep after all that, the a < 3 is basically ignored example: say a = 2 sure 2 is less than 3 so that's why a = 2 works for a < 3 but a = 2 does NOT work for a < -2 so that's why a < -2 and a < 3 combine to a < -2
oh okay thts wht I thought:)
what is the solution of 1/2x-8=3/2x+2? I got x=5 is that right?
can you draw it out? I'm not sure if the 1 is over the 2, 1 is over the 2x, or if 1is over the 2x-8
