9x8y12 it a lot of work to do so I don't want to type how to do the problem
Answer:
-five sixths= -5/6
six fifths= 6/5
times= multiplication
so , -5/6 x 6/5 = -1
(both sixes get cancelled and the fives also get cancelled to get -1/1 = -1)
Hello,
Yes of course 0.4 or 4/10 is a rational number :)
Have a nice day :)
5x-23=87
add 23 to both sides
5x=110
divide both sides by 5
x=22
To check your answer...
5(22)-23=87
110-23=87
87=87
