Answer:
CD = 45
Step-by-step explanation:
CE = 180
( x + 6 ) + ( 4x - 21 ) = 180
5x - 15 = 180
5x = 195
x = 39
substitute x in CD
CD = x + 6
CD = 39 + 6
CD = 45
8(8-6v)= using the distributive property
8*8 = 64
8*6v = 48v
8(8-6v) = 64-48v
We can just divide the two numbers.
13/20 = 0.65
Where 100% = 1
So 65%
