Answer: (7,5) X=7 and Y=5
Explanation:
Add the two equations together to eliminate y from the system.
x-y=2 + x+y=12
= 2x = 14
Divide both sides by 2
x=7
Substitute the value found for x into one of the original equations to solve for y
(7)-y=2
Move all terms to one side to make it easier
-y=2-7
Subtract
y=5
Answer:
87777777777777777777777777
Step-by-step explanation:
AB ≅ DC and AD ≅ BC
slope of BC = slope of AD (m = 1/3), slope of AB = slope of DC (m = 3/1)
opposite sides are congruent and parallel so ABCD is a parallelogram.
Answer: parallelogram
Answer:
x = -4
Step-by-step explanation:
Lets divide both the sides by -3.
Answer:
3.25 pounds
Step-by-step explanation:
x + 4 (1/2) + 3 (1/2) = 11
x + 4.25 + 3.5 = 11
x + 7.75 = 11
x = 11 - 7.75
x = 3.25 pounds
