Answer:
$1.25
Step-by-step explanation:
The graph shows that 3 pens cost $3.75 which means each pen costs more than $1 so we know that the greater number will be the numerator in our division equation. Divide 3.75 by 3 to get the unit rate.
3.75/3=1.25
Each pen costs 1.25
You can check your work by plugging it into the other points.
6*1.25=7.5 -So that second point is correct
9*1.25=11.25- The third point is also correct meaning we got the right answer
Answer: your answer would be 5/16th :)
You can multiply either the top or bottom equation by -1 so lets say you apply it to the bottom equation it’ll look like this:
-9x + 9y = 18
6x - 9y = 12
then the +9y and -9y will cancel out
-9x = 18
6x =12
then you add the two equations together
-3x = 30
divide both sides by -3
x = -10
