_6. ifx-12 = -15, find the value of 4-X

Mathematics
1 answer:
melisa1 [442]3 years ago
8 0

First find the value of "x", by isolating/getting the variable "x" by itself in the equation:

x - 12 = -15   Add 12 on both sides to get "x" by itself in the equation

x - 12 + 12 = -15 + 12

x = -3    

Now that you found the value of x, you can use it to find the value of 4 - x

4 - x        Substitute/Plug in -3 for "x"

4 - (-3)    [two negative signs cancel each other out and become positive]

4 + 3

7         The value of 4 - x is 7

<h3>You have the correct answer</h3><h3>Interest rate = 21.5%</h3>

===============================================

Work Shown:

i = P*r*t .... simple interest formula

i = simple interest

i = 2075-1000 = 1075

P = 1000 = amount borrowed (principal)

r = unknown interest rate

t = 5 = time in years

So,

i = P*r*t

1075 = 1000*r*5

1075 = 5000r

5000r = 1075

r = 1075/5000

r = 0.215

r = 21.5%
