Z=kx, 30=8k, so k=30/8=15/4 and z=15x/4, so when x=4, z=15.
Answer:
5%
Step-by-step explanation:
You want to find r when ...
I = Prt
is equal to P and t=20.
P = Pr·20 . . . . fill in the problem values
1/20 = r = 0.05 = 5% . . . . divide by 20P
The simple interest rate is 5%.
Step-by-step explanation:
- (-2)4 = -8
- -8 +(-10)= -18
