3x-5y=10
-5y=-3x+10
y=3/5x-2
(10)1/3=10/3=3.33333
(5)1/3=5/3=1.666667
3.33333>1.66667
Hence (10)1/3>(5)1/3 (proven)
Answer:
x = 70
Step-by-step explanation:
Properties of a parallelogram.
1). Pair of opposite sides of a parallelogram are equal in measure and parallel to each other.
2). Opposite angles of a parallelogram are equal in measure.
3).Adjacent angles of a parallelogram are supplementary.
By the second property,
(2x - 30) = (x + 40)
2x - x = 30 + 40
x = 70
Step-by-step explanation:
Scale factor
= Side length of big triangle / Side length of small triangle
= 12/5 = 24/10 = 33.6/14 = 2.4.
