Step-by-step explanation:
second one because
only x+2y=8 passes through the point (2,3)
the proof is 2+2*3=2+6=8
if we replace the given point to the other equations we will take wrong results for example
first equation
x+2y=4. 2+2*3=2+6=8 that is not equal to 4
Answer:
4 2/4
Step-by-step explanation:
4 1/2 + 1/2 = 4 2/4
i just added em up
Answer:
C
Step-by-step explanation:
Find area of all trinagles and subtract that by total area of square.
Answer:
x ≈ 4
Step-by-step explanation:
We use tan∅ to solve this:
tan30° = x/7
7(tan30°) = x
x = 4.04145
Remember that tangent is opposite over adjacent.
Its A 7 considering you minus 13 which is 2 or 3 cups and 6 which is 6 or 7 cups, so 13-6=7
