If E is the midpoint, DE and EF are equivalent.
2x+4=3x-1
4=x-1
5=x
Plug the value of x in
2(5)+4
14
3(5)-1
14
14+14=28
Final answer: DE=14, EF=14, DF= 28
I hope this helps you
2.(7R-15+2R-3/2+7R)-4
2. (16R-33/2)-4
2.16R-2.33/2-4
32R-33-4
32R-37
There are 12 months in a year and each year it decreases 6% so therefore each month it decreases .5%.
If you were asking the the amount it depreciates each month then you take .5% or .005 of 12000 which is 60 dollars a month.
