Answer:
0.85 of the original piece of lumber remains.
Step-by-step explanation:
Well, this lumber piece of lumber started as 2.5 meters long. Then, a 1.65 meter piece was cut off of it. All we need to do is subtract.
2.5 - 1.65 =
2.50 - 1.65 = 0.85.
Therefore, 0.85 of the original piece of lumber remains.
Hope this helps! :)
Answer:
A system of linear equations can have no solution, a unique solution or infinitely many solutions. A system has no solution if the equations are inconsistent, they are contradictory. for example 2x+3y=10, 2x+3y=12 has no solution. is the rref form of the matrix for this system.

Answer:
A. To sum up the essay's key points and reasons
Answer:
y = 2
Step-by-step explanation:
Given
(y + 7) = 3(y - 1)
Multiply both sides by 3 to clear the fraction
y + 7 = 9(y - 1) ← distribute
y + 7 = 9y - 9 ( subtract 9y from both sides )
- 8y + 7 = - 9 ( subtract 7 from both sides )
- 8y = - 16 ( divide both sides by - 8 )
y = 2
