Answer:
x = 8
Step-by-step explanation:
3 (x - 5) + 7x = 65
3x - 15 + 7x = 65
10x - 15 = 65
10x = 80
x = 8
10-11= -1 You could also input this number on a calculator
The standard compound interest formula is
Future value after x years with an annual interest of i
=Present Value (1+i)^x [which is an exponential function]
for given present value of $360. interest=0.03 (3%) and a total of x years, above equation reduces to
Future value after x years
=360(1.03^x)
First you compare the denomonators and see if they have any common multiples, then what you do to one side you do to the other so you multiply so you get the same number on both denomonators.finally you multipybthe same number you did ti he botto. to the top.p.s. your welcome
