Answer:
A) 7x + 3y = -8
B) -4x - y = 6 Multiplying B) by 3
B) -12x -3y = 18 then we add A)
A) 7x + 3y = -8
-5x = 10
x = 2
y = -2
Answer is the first one (2, -2)
Step-by-step explanation:
Triangle area is 1/2 bh
So 11.9 is about 12, 7.1 is about 7.
7x12 = about 84 sq, cm
1/5 3/5 7/10 4/5 Change the denominators all to 10 to be able to but them in order
Hey there! :)
Answer:
