You would do 14*4 which equals 56 so if you did that to every side you would get the number of the bigger shape so you would to find x is 3*4 which equals 12 so the answer is x=12
Answer:
131 and 49
Step-by-step explanation:
Supplementary angle means 180° when all angles are added together.
First angle: (x + 82)
Second angle: x
(x + 82) + x = 180
2x + 82 = 180
2x = 98
x = 49
First angle: 49 + 82 = 131°
Second angle: 49°
Answer:
x = 5
Step-by-step explanation:
(since the equations are equal to eachother, add similiar factors)
4x - 3 = 2x + 7
+3. -2x
2x = 10
<em>Simplify</em>
x = 5
Answer:
(-30, 10)
multiply -20/60 by -0.5 each and you get 10/-30
this is the only pair achievable by proportion.
