True [87]3 years ago
8 0

Answer:

34 sold for $20

55 sold for $35

Step-by-step explanation:

20x+35y=2605

y=(98-x)

20x+35(89-x)=2605

Solve for x

20x+3115-35x=2605

20x-35x=2605-3115

-15x=-510

x=34

Please help<br><br><br>A) x= -4 and 4<br><br>B) x=4 and 6<br><br>C) x=2 and 8<br><br>D) no solution
Neporo4naja [7]

Answer:

No solutions

Step-by-step explanation:

|-2x-10| + 4 = 2

Subtract 4 from each side

|-2x-10| + 4-4 = 2-4

|-2x-10|  = -2

The absolute value is negative so there are no solutions.

Absolute values are always positive, so they cannot be negative.
