5. 2 lbs and 13 oz
6. 6500 lbs
16 oz= 1 lb
1 T = 2000 lbs
The second option would be parallel
Answer:
The millionethed in this case
The best way to find fractions that are equal is to find a common factor and divide/multiply them.
So in 25/35 you can easily see that 5 goes into both SO...
25/35 / 5/5 = 5/7
25/35 = 5/7
Putting the equations into standard form helps me identify dependent and inconsistent systems. In standard form, the leading coefficient is positive, and all numbers are mutually prime (have no common factors).
1.) 2x + y = -9 . . . . . . multiply the original equation by -1
... 3x - 4y = -8 . . . . . . the system is independent
These two equations will give rise to a single solution.
_____
2.) 4x + y = 4 . . . . . . divide the original equation by 3
... 4x + y = 5 . . . . . . . the system is inconsistent
These two equations describe parallel lines, so will not have a point of intersection. There are no values of x and y that can satisfy both equations.
