Answer:
4 - x =3
2x*2 +x =5 = 4-1 = 5
We input 5 as we already have found fx
(5)4-x(5) = 20-5
x=15

Step-by-step explanation:
<u>Find the missing angle:</u>
- m∠L = 180° - 60° - 45° = 75°
<u>Use the law of sines to determine the lengths of the sides:</u>
- LM / sin ∠K = KM / sin 75°
- 12 / sin 60° = KM / sin 75
- KM = 12 sin 75° /sin 60° = 13.4 (rounded)
- KL / sin ∠M = LM / sin ∠K
- KL / sin 45° = 12 / sin 60°
- KL = 12 sin 45° / sin 60° = 9.8 (rounded)
<u>Find perimeter:</u>
- P = 12 + 13.4 + 9.8 = 35.2

hi
Step-by-step explanation:
We see a set of linear equations. Hence, a system of linear equations. So we solve them by process of elimination, multiplying the top equation by 5 to eliminate first such that
(2x+y=20)*5
6x-5y=12
-----------------------------------------
10x+5y=100
6x-5y=12
--------------------------------
16x = 112 .............After dividing 16 we get
x = 7
Now we plug x = 7 back into the original first equation to obtain the y value such that
2(7) + y = 20
12 + y = 20
-12 -12
------------------
y = 8
I hope this helped!
This is the concept of algebra, to solve the inequality we proceed as follows;
|8m+4|<12
given that the absolute value is represented by positive and negative values, we shall have:
-(8m+4)<12
-8m-4<12
-8m<12+4
-8m<16
thus;
m>16/(-8)
m>-2
also:
8m+4<12
8m<12-4
8m<8
m<8/8
m<1
hence the answer is -2<m<1
