4a - 5 + 2a + 9 = 28
BaLLatris [955]

Answer:a=4

Step-by-step explanation:

Simplifying

4a + -5 + 2a + 9 = 28

Reorder the terms:

-5 + 9 + 4a + 2a = 28

Combine like terms: -5 + 9 = 4

4 + 4a + 2a = 28

Combine like terms: 4a + 2a = 6a

4 + 6a = 28

Solving

4 + 6a = 28

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + 6a = 28 + -4

Combine like terms: 4 + -4 = 0

0 + 6a = 28 + -4

6a = 28 + -4

Combine like terms: 28 + -4 = 24

6a = 24

Divide each side by '6'.

a = 4

Simplifying

a = 4

You lend out S5500 at 10% compounded monthly. If the debt is repaid in 18 months, what is the total owed at the time of repaymen
GrogVix [38]

Answer:

$6386.1140

Step-by-step explanation:

Using the compound interest formula :

A = P(1 + r/n) ^nt

P 5500 ; rate, r = 10% = 0.10 ; t = 18 months = 18/12 = 1.5 years,

Compounding times per period = 12 (monthly)

A = 5500(1 + 0.1/12)^12*1.5

A = 5500(1 + 0.0083333)^18

A = 5500(1.0083333)^18

A = 5500 * 1.1611116

A = 6386.1140

Hence, amount to be repaid = $6386.1140
