Answer:
68
Step-by-step explanation:
LM + MN = LN
x + 7 + 3x + 20 = 6x - 5
4x + 27 = 6x - 5
-4x -4x
27 = 2x - 5
+5 +5
32 = 2x
÷2 ÷2
16 = x
MN: 3x + 20
3(16) + 20
48 + 20
100% increase
Calculate percentage change
from V1 = 20 to V2 = 40
(V2−V1)|V1|×100
=(40−20)|20|×100
=2020×100
=1×100
=100%change
=100%increase
8÷2= 4
15-4= 11
