Answer: 
Step-by-step explanation:
In order to solve this exercise it is important to remember the multiplication of signs. Notice that:
In this case you have the following expression given in the exercise:
Where the variable is "j".
When you multiply signs, you get:
Now you need to identify that like terms and then you need to add them (or combine them). So, applying this procedure you get that the simplified form of the expression is the shown below:
As you can observe, you get a 2nd degree binomial.
The answer is D
Because if you replace the variables just by testing them they give the answer as X=-3 and Y=3.
In which replacing:
3(-3)+5(3)=6
and with the other equation we've got:
4(-3)+2(3)=-6
so they comply with the required to be the correct answer, even though you can make a system of equation.
36204 turns into 36200, and 40918 turns into 40920
Answer:
41/62 = .66
Hope this helps :)
Step-by-step explanation:
41/4 / 31/2
keep change flip
41/4 * 2/31
82/124
Simplify
82/124 = 41/62
41/62 = .66
Because the three numbers are consecutive, if the first one is x, the second should be x+1, and the third one is x+2
the three numbers add up to be 5982, so
x+(x+1)+(x+2)=5982
3x+3=5982
3x=5979
x=1993
1993,1994,1995
