Answer:
0a = 0
Step-by-step explanation:
Expand
8a + 32 + 4 = 36 + 8a
Rearrange equation
8a - 8a = 36 - 32 - 4
0a = 0
Answer: Simple interest rate = 3%.
Step-by-step explanation: We are given invested amount = $5000.
Number of years of investment = 4 years.
Interest earned = $600.
Simple interest formula.
I = P R T.
Where I is the earned interest, P is the invested amount , R is the rate of interest and T is the time in years.
Plugging values in formula, we get
600 = 5000 × R × 4
600 = 20000R.
Dividing both sides by 20000, we get

0.03 = R.
Multiplying by 100 to convert it in percentage, we get
0.03 × 100 = R
R = 3 %.
Answer:
Step-by-step explanation:
5x - 16 = 4x + 6
x - 16 = 6
x = 22
5(22) - 16 = 110 - 16 = 94
4(22) + 6 = 88 + 6 = 94
