Solve the equation for x:
4x+12=48
Subtract 12 from both sides: 4x=36
Divide 4 from both sides to isolate x: x=9

Solve using inverse operations <br><br> 1. 5x + 10 = 15 <br><br><br> 2. r/4 - 1 = 4

adell [148]

1)

5x + 10 = 15
- 10 - 10

5x = 5

x = 1

2)

r/4 - 1 = 4
+ 1+ 1

r/4 = 5
*4 *4

r = 20

Encik Zulhazim deposited RM8000 in a fixed deposit account at Bank T for 2 years with interest rate of 5% per annum. What is the

creativ13 [48]

Answer: $34.08

<u>Step-by-step explanation:</u>

$\text{Compound Interest}:A=P\bigg(1+\dfrac{r}{n}\bigg)^{nt}\\\\\bullet A=\text{accrued amount (final balance)}\\\bullet P=\text{principal (amount invested)}\\\bullet r=\text{interest rate (convert percentage to a decimal)}\\\bullet n=\text{number of times compounded (in one year)}\\\bullet t=\text{time (number of years)}\\\\\\\underline{\text{Given:}}\\\bullet P=8000\\\bullet r=5\% (0.05)\\\bullet n=3\ \text{(every 4 months is 3 times per year)}\\\bullet t=2$

$A=8000\bigg(1+\dfrac{0.05}{3}\bigg)^{3(2)}\\\\\\A = \large\boxed{8834.08}$

$\text{Simple Interest}:A=P(1+rt)\\\\A=8000+8000[1+0.05(2)]\\\\A=\large\boxed{8800.00}$

Difference = Compound Interest - Simple Interest

= 8834.08 - 8800.00

= 34.08
