12.42 .8) how do you get it solved not just the anwser

12.42 -(-4.8) = 17.22

Step-by-step explanation:

1.  The most important thing to note is the double negative signs, separated by the paranthesis.  When 2 signs, numbers, variable, etc... are separated by a ( ) or simply beside each other, such as 2x or 4(6), you would multiply the 2 numbers.

2.  In this equation, note that the negative sign is directly beside the (4.8):

    (-)(-4.8)  This means that you would multiply the negative sign or -1 by the -4,8.  Remember multiplication rules with signs: a negative (-) number x a negative (-) number = a POSITIVE number.

3.  Therefore,  (-)(-4.8)  is looking at the problem as (-) x (-4.8) = +4.8.

4.  Note that at this point, the equation becomes an addition problem:

    12.42 + 4.8 = x

5.  Use your calculator to solve or the CORRECT way of simply lining up the decimals, and, there's your

   12.42 + 4.8 =  17.22

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
