you don't know the answer?! Come on folk you tweaking.
Step-by-step explanation:
All that are true:
sin(C) = square root 3/2
tan(C) = square root 3
sin (B) = 1/2
Answer:
x+y=5a
5a is added to b which is the sum of x and y multiplied by 3. That is, b=x+y×3=5a×3=15a
Since, 5a is added to b= 5a+15a=20a,
Answer:
C. II only
Step-by-step explanation:
Basically all you need do is plug these answers in and if the complete the inequality to make a true statement.
Yes i know no body want to do that but that whats need to be done lol.
once i plug 7 12/7+8 = 12.83
12.83>20
is incorrect
so we need continue
7*2.5+8>20
7*2.5= 17.5
17.5+8= 25.5
25.5>20
this a true statement
so we know 2.5 is an answer
now we need plug in -3
7*-3= -21
-21 +8 = -13
-13>20
this is incorrect
5/8 = 0.625
6 / 9.6 = 0.625
12.8 * 0.625 = 8
x = 8
