1 plus 2 = 3, then u do 6/2 (3), then 3x3 = 9
Answer: 2/15
Step-by-step explanation:
25-21/30 = 4/30
4/30 = 2/15
1 and 5/16 pounds
Divide 7/8 with 2/3
When they have no solutions, the lines are parlaell, or they have the same slope but different y intercept
example
3x+2y=2 and
3x+2y=4 are paralell
also
y=3x+2 and
y=3x+4 are also parlell, no solutions
infinite solutions are when they are the same line
they have the same slope and y intercept
to find out, simplify
3x+2y=4 and
6x+4y=8 are smae lien
also
y=3x+2 and
2y=6x+4 aer the same line
1 solution is when it is none of the above things
a normal thing, where the slopes are differnet
example
y=2x+2
y=3x+2
I hope this helps you understand the steps to get your answer...
