Answer:
8x or x8
Step-by-step explanation:
x - 2y = 5
-3x + 2y = 7
-----------------add
-2x = 12
x = 12/-2
x = -6
-3x + 2y = 7
-3(-6) + 2y = 7
18 + 2y = 7
2y = 7 - 18
2y = - 11
y = -11/2
solution is : (-6,-11/2)...x = -6 and y = -11/2
C is your answer.
Without calculating anything else, you can look at the minimum and maximum values in your data set of 6 and 35. C is the only one that has those correct.
Just make sure that the numbers are in order before you analyze.
You can use the CPCTC (Corresponding Parts of Congruent Triangles are Congruent) property. This means that when two triangles are congruent, all the corresponding parts are congruent to each other.
Have an awesome day! :)
