Answer:

Step-by-step explanation:

The absolute value function always gives a positive value, however the expression inside can be positive or negative, that is

0.5x + 1 = 5 ( subtract 1 from both sides )

0.5x = 4 ( divide both sides by 0.5 )

x = 8

- (0.5x + 1) = 5

- 0.5x - 1 = 5 ( add 1 to both sides )

- 0.5x = 6 ( divide both sides by - 0.5 )

x = - 12

There are 2 solutions to the equation

x = 8 or x = - 12

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

$k = 59(f - 32) + 273.15$

Subtract the sides of the equation minus -273.15

$k - 273.15 = 59(f - 32)$

Divided the sides of the equation by 59

$\frac{k - 273.15}{59} = \frac{59}{59} (f - 32) \\$

$\frac{k - 273.15}{59} = f - 32 \\$

Subtract the sides of the equation plus 32

$\frac{k - 273.15}{59} + 32 = f \\$

And we're done.

Thanks for watching buddy good luck.
