Answer:

x = 3

Step-by-step explanation:

First we know that you have to do parenthesis because, of PEDAS so the problem would look like 4x - (x-5)+3=-1. You would first because, it is always 1 outside of parenthesis it would now look like 4x - x +5 +3=-1. Next you would combine like term 3x +8 = -1. Next you would subtract 8 from both sides 3x = 9. Next you would divide 3 from both sides. x=3

Therefore your answer would be x = 3

You have three online accounts and three different banks valued at: bank “A” $250.67, 12% interest, bank “B” $765.13, 7% interes
larisa [96]

The average interest gained from three accounts in one year is $913.224

<u>Explanation:</u>

Given:

Bank A:

Principal, P₁ = $250.67

Rate, r₁ = 12 %

Bank B:

Principal, P₂ = $765.13

Rate, r₂ = 7 %

Bank C:

Principal, P₃ = $28500.36

Rate, r₃ = 9 %

Interest from Bank A:

Interest = \frac{p X r X t}{100}\\\\I = \frac{250.67 X 12 X 1}{100} \\\\I = 30.0804

Interest from Bank B:

Interest = \frac{p X r X t}{100}\\\\I = \frac{765.13 X 7 X 1}{100} \\\\I = 53.5591

Interest from Bank C:

Interest = \frac{p X r X t}{100}\\\\I = \frac{28500.36 X 9 X 1}{100} \\\\I = 2565.0324

Average interest gained from three accounts in one year :

I = \frac{30.0804+53.5591+2656.0324}{3} \\\\I = 913.224

Therefore, average interest gained from three accounts in one year is $913.224
