The First One
The Third One
The Forth One
The others result in a lower number than what they are supposed to be. The 3 correct ones end with the exact number of the equations solution number.
X=price of one jumbo popcorn
y=price of one chocolate chip cookies
$5.00=$5.00(100 cts / $)=500 cts
$6.00=$6.00(100 cts / $)=600 cts
We suggest this system of equations:
x+2y=500
x+4y=600
we solve this system of equations by reduction method.
-(x+2y=500)
x+4y=600
----------------------
2y=100 ⇒ y=100/2=50
x+2y=500
x+2(50)=500
x+100=500
x=500-100
x=400
solution: one chocolate chip cookie cost 50 cts.
Answer:
slope = 12/5 or 2.4
Step-by-step explanation:
(-2,-7), (3,5)
(5 - (-7) / 3 - (-2)) = (12 / 5)
slope = 12/5 or 2.4

Answer:
Therefore the Final Solution is x = 2 and y = 7
i.e (2 ,7)
Step-by-step explanation:
Given:
...............Equation ( 1 )
...............Equation ( 2 )
..............Equation ( 3 )
To Find:
x = ?
y = ?
Solution:
Substituting Equation ( 3 ) in Equation ( 1) we get
Now Substituting x = 2 in Equation ( 3 ) we get
Therefore the Final Solution is x = 2 and y = 7
i.e (2 ,7)
