ans:(x=6)
6x+54=90
6x=36
6x/6=36/6
x=6
x = 6.
We know that the right angle is 90°. So:
(x + 54)° + 5x° = 90°
x° + 54° + 5x° = 90°
6x° + 54° = 90°
6x° = 90° - 54°
x = (90° - 54°)/6°
x = 36°/6°
x = 6
Then, solving for x we obtain:
5x° = 5(6)° = 30°
(x + 54)° = (6 + 54)° = 60°

2/3 is the same 4/6
7/2 is the same as 21/6
4/6 + 21/6 = 25/6
So the answer is 25/6, not 25/5.
Yeah the other guys right

Answer:
-0.5
Step-by-step explanation:
σM=σ/√N
=9/√36
=9/6
=3/2=1.5
Z=(x-μ)/σ/√N
=(19.5-24)/9/√36
=-4.5/1.5=-3
The probability that the sample mean will be larger than 19.5 = -0.5
P(>19.5)=P(Z>-3)= -0.5
You buy 6 shirts. So $77 minus $5=$72
Then you divide $72 by $12 and you get 6 shirts
