Answer:
ok i will
Step-by-step explanation:
The equation would be ... Y = 2x + (-5)
8/9 - 2/3 = 8/9 - 6/9 = 2/9 of a pound left
She had 8/9 of a pound of birdseed to begin with. She used 2/3 of a pound of birdseed into her feeders. You have to get a common denominator, would be 9 and when you subtract what she used from what she had you get 2/9 of a pound of birdseed left.
It takes them 1 7/8 hrs to complete the job together.
How:
Fred = 3 hrs
Jason = 5 hrs
1/3x + 1/5x = 1/x
3x x 5x = 15 —> 3x/15 + 5x/15 = 15/15
3x + 5x = 8x —> 8x/15 = 1.875 = 1 7/8 hrs
<span>6x + 10 = 4x -8
6x-4x = -8 - 10
2x = -18
x = -9
