No because there are no parentheses, therefore no distributive property
3x-y=2....(i)
2x-y=3.....(ii)
now adding the eqn I and ii ,
3x-y=2
2x-y=3
+ + +
5x=5
x=1
Now substituting the value of x in eqn I
3×1-y=2
3-y=2
-y=-1
y=1
4/50 as a decimal is .08
Divide 4 by 50
Answer:
No, they are not congruent
Step-by-step explanation:
By CD and EF being congruent, we want to know if they are equal.
What we can simply do here is to find the distance between the points present.
That is, the distance between C and D, the distance between E and F
To get the distances between two points , we use the following equation
D = √(x2-x1)^2 + (y2-y1)^2
For CD, we have
D = √(6 -(-1)^2 + (-7 + 7)^2
D = √(7)^2 = 7 units
For EF, we have
D = √(5-5)^2 + (-5-3)^2
D = √(-8)^2
D = √(64) = 8 units
This clearly shows that they are both not congruent
