years. What is the annual interest
rate?

HURRY HELP

Answers

Answer:

2.2% per year

Step-by-step explanation:

Problem:

You deposit $500 into a bank account and received $55 simple interest after 5 years. What had been the interest rate?

Result:

The interest rate was 2.2% per year.

Explanation:

Find interest rate by using the formula I = P*i*t , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.  In this example I = $55, P = $500 and t = 5 years, so

i = 55/500*5

i=0.022 = 2.2% per year

Solve the pair of simultaneous equations and leave the answer as a fraction in

its lowest term. 2x − 3 = y, x+ y= 8​

Answers

Answer:

x = 11/3 = 3 2/3

y = 13/3 = 4 1/3

Step-by-step explanation:

Here, we want to solve the system of equations simultaneously

x + y = 8

2x -3 = y

From the second equation, we have an equation for y

we can simply proceed to substitute this into the first equation

x + 2x - 3 = 8

3x - 3 = 8

3x = 8 + 3

3x = 11

x = 11/3

Recall;

y = 2x - 3

y = 2(11/3) - 3

y = 22/3 - 3

y = (22-3(3))/3

y = (22-9)/3 = 13/3
