Answer 2

-1 3/8 and -1.375

Explanation:

To solve for x in the equation -2.25 + 0.4x = -2.8, we can start by isolating the variable term (0.4x) on one side of the equation:

-2.25 + 0.4x = -2.8

0.4x = -2.8 + 2.25

0.4x = -0.55

Next, we can divide both sides by 0.4 to solve for x:

x = -0.55 / 0.4

x = -1.375

As a mixed number, -1.375 can be written as:

-1 3/8

As a decimal, -1.375 is already in decimal form.
