Well, first, you need to know what you want to 'do' to it.
You want to find the description of what 'x' has to be in order to
make that inequality a true statement. Here's one way to do it:
4/5 x > 14
Multiply each side by 5 : 4 x > 70
Divide each side by 4 : x > 17.5 .
That's it. As long as 'x' is more than 17.5 ,
the original inequality is true.
first one is 40 and then 65 and then 65 again
Answer:
sin x = 39/89 cos x = 80/89 tan x = 89/80
Step-by-step explanation:
SOA CAH TOA
sin = opp/adj
cos = adj/hyp
tan = opp/adj
1) 1/3x - 2/3 = -18
2) 1/3x - 2/3 + 2/3 = -18 + 2/3
3) 1/3x = -54/3 + 2/3
4) 1/3x = -52/3
5) (1/3x) divided by 1/3 = -52/3 divided by 1/3
6) x = -52/3 x 3/1
7) x = -52
