5x - 4 = -3x + 12. Solve for x
leva [86]

5x - 4 = -3x + 12.

5x+3x-4= 12

move -4 to the other side

sign changes to +4

5x+3x-4+4= 12+4

8x= 16

divide by 8 for both sides

8x/8= 16/8

x= 2

The total simple interest on $1600 invested for five years is $224. What is the percentage rate per annum?
mash [69]

Answer:

The percentage rate per annum is 2.8%

Step-by-step explanation:

We need to multiply the principal by the time, then divide the interest by the product of P×T, so:

1,600 × 5 = 8,000

224 ÷ 8,000 = 0.028

Then we convert our final product to a percentage.

0.028 to a percent is 2.8%
