Step-by-step explanation:
23.75-3.75=21
21÷4=5.25
If BE=30 then you would have to find out what x is. 8+12=20 so all you need is 10 more to equal BE.
Answer:
1+i
Step-by-step explanation:
The explicit formula for the compound interest geometric tell us: If P1 is invested at an interest rate of i per year, compounded annually, the future value Pn at the end of the nth year is:

For example if you have $10 at 5% at an interest rate of 5% per year.
Then if you want to know the amount of money at the end of the 2, 3 and 4 year, you have:
n=1 year P1=10
n=2 year


=10,5
n=3 year


=11.025
n=4 year


= 11.57625
Answer:
x=9
y=6
Step-by-step explanation:
x+y=15 .............(i)
x-y=3...........(ii)
Subtracting equation (ii) from equation (i)
or, x+y -(x-y)=15-3
or, x+y-x+y=12
or, 2y=12
or, y=12/2
∴y=6
Now,
Putting the value of y on equation (i),
or, x+6=15
or, x=15-6
∴x=9
