How do you solve simple interest $600 at 5% for 2 years and %1500 at 4% for 4 years

1. $60

2. $240

Step-by-step explanation:

Use the formula for simple interest. Put your numbers in the formula and do the arithmetic.

i = Prt . . . . where i is the interest amount, P is the principal, r is the rate, t is the time period

1. P = $600, r = 0.05, t = 2, so you have ...

i = $600·0.05·2 = $60

__

2. P = $1500, r = 0.04, t = 4, so you have ...

i = $1500·0.04·4 = $240

A.  x = 5 (Equation below)

B. AC = 9 | BD = 9

Step-by-step explanation:

A. Since we know the diagonals of an isosceles trapezoid are congruent, we know that the two bottom parts of the diagonal BD (2x - 8 and x - 4) are congruent to the diagonal AC (x + 2) . This means you can just equal them together and get the value of x:

2x - 8 + x - 4 = x + 2

3x - 12 = x + 2

3x = x + 14

2x = 14

x = 7

B. Just plug in 5 for x:

AC = x + 2 = 7 + 2 = 9

BD = 2x - 8 + x -4 = 3x - 12 = 21 - 12 = 9
