Answer:
5 x 0.6 = 5 x 6tenths, as 6/10 = 0.6
= 30 tenths
7 x 0.8 = 7 x 8tenths, as 8/10 is 0.8
= 56 tenths
Step-by-step explanation:
If you really want a more detailed explanation, just reply to this message.
It is .6 because 6 doesn't repeat and by the 10 you go left one
So if we want to know the common solution(s) to a system of 2 equations, So we can just set both equations equal to each other and solve for the x value(s). That’s where I start below;
2x^2-13x+21 = 2x^2+9x-56
2x^2 cancels out and moving everything to one side and anything with an x variable to the other side we have then;
-22x=-77
22x=77 by cancelling the negative signs
x=77/22 therefore x=7/2 or 3.5
Hope this helps you. Any questions please ask.
The distance between -2 and -1 1/2 is 1/2:
-2+1/2=-1 1/2
-1 1/2 =-1 1/2
I was trying to show my work but hope this could help you
