Find the approximate value
assume
------> approximate value of the area
Answer:
x=5, y=6. (5, 6).
Step-by-step explanation:
-6x+6y=6
-6x+3y=-12
---------------
simplify -6x+6y=6 into -x+y=1 and y=1-(-x)=1+x
-6x+3(1+x)=-12
-6x+3+3x=-12
-3x=-12-3
-3x=-15
3x=15
x=15/3
x=5
-6(5)+6y=6
-30+6y=6
6y=6-(-30)
6y=6+30
6y=36
y=36/6
y=6
X - the length of the model:
36.25 : 9 = x : 1.25
9 x = 36.25 · 1.25
9 x = 45.3125
x = 5.03 ≈ 5 inches.
