Answer:
The required expression would be 
Step-by-step explanation:
Since, the amount formula is,

Where,
P = invested amount,
t = number of periods,
r = rate per period,
Given,
The invested amount at month 1, P = 4,
Number of periods from month 1 to month 4, t = 3
Amount at the end of fourth month, A = 256.
By substituting the values,




Hence, the amount of money at the end of t months.

You do 600 divided by 2700 and you end up with 22/100 or 0.22 as a decimal. So if 0.22 or 22/100 are venimous then 78/100 or 0.78 are non venimous. I understand its a bit confusing and i can simplify it for you but still I hope this helps :)
Answer:
1866
Step-by-step explanation:
1866 because the next digit is zero , therefore the value to the nearest whole number is 1866.
Answer:
C.
Step-by-step explanation:
Your fractions are missing there fraction bars:
3/4 (20y − 8) + 5 = 1/2 y + 1/4 (20y + 8)
15y − 6 + 5 = 1/2 y + 5y + 2
15y − 1 = 11/2 y + 2
A. 11/2y and 2 aren't like terms because one contains the variable y and the other contains no variable
B. The distribute property can't be used there because you don't have 15(y-1) you have 15y-1
C. Subtracting 11/2y sounds like a good step because there is a y term on the opposing side.
15y-1=11/2y+2
Subtracing 11/2y on both sides
9.5y-1=2
That looks pretty good because then you would add 1 on both sides giving:
9.5y =3
Last step would get the y by itself which is dividing both sides by 9.5 giving you 6/19.
D. You could actually do this but it doesn't help you get x by itself. The equation would look like this: 15/2 y-1/2=11/4 y+1
Answer:
answer for this solution is 2,3,4.
