Answer:
n = 3.666 or (3 and 2/3)
Step-by-step explanation:
4.5n + 2.5 = 19
4.5n = 19 - 2.5
4.5n = 16.5
n = 16.5 / 4.5
n = 3.666 or (3 and 2/3)
Answer:
x =5
Step-by-step explanation:
Tangents from same external point have equal length.
KJ = LJ
4x - 1 = 2x + 9
Add 1 to both sides
4x = 2x + 9 + 1
4x = 2x + 10
Subtract '2x' from both side
4x - 2x = 10
2x= 10
Divide both sides by 2
x = 10/2
x = 5
M = 2/5 x b = 4 because u divided both by 5
