6 5/6 - 5 1/12
6 5/6 x 2
6 10/12 - 5 1/12
6-5=1
10-1= 9
( You don't subtract the 12s in subtraction)
1 9/12
Simplified
1 9/12 both divided by 3
1 3/4
Final answer 1 9/12
Simplified answer 1 3/4
The <span>height of the tower. is 27 m
Now, we write h/x = tan 45
i.e h/x = 1
i.e h = x ...........................1.
Now, h/(x+20) = tan 30
i.e </span> (x+20)/h = 1/tan 30
or (x+20) = 1.73h
or from equation 1 ,
h+ 20 = 1.73 h
20 = 1.73h - h
h = 20/0.73
or h = 27.39 = 27 m
Answer:
-8
Step-by-step explanation:
12<-3 (x + 4)
1. distribute to the -3 to the x and 4 and should get
<em><u>-3*x = -3x</u></em>
<em><u>-3*4 = -12</u></em>
<u>12< -3x - 12</u>
2. now you get rid of the common factors which is -12 so add 12 to both sides and should get
-12+12=0
12+12=24
<u>24< -3x</u>
3. to get x by itself you will have to get rid of -3, so how to do that is divide -3 to both side and should get
-3x/-3= x
24/-3= -8
<u>-8<x</u>
