After getting 5 new rocks, george gave half of his rock collection to susan. if george gave susan 36 rocks, which equation could be used to determine how many rocks george started with?
a.1/2x=36+5
b.1/2(x-5)=36

d.1/2x+5+36

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
