josh bought followers for nancy. he spent a total of $14.85 and bought 13 flowers. if he knows lilies cost $1.25 and tulips cost

Serjik [45]

Answer:

x = lillies

y = tulips

x + y = 13

1.25x + .90y = 14.85

-1.25x - 1.25y = -16.25

1.25x + .90y = 14.85

-0.35y = -1.40

y = 4 tulips

x + 4 = 13

x = 9 lillies

(9 lillies, 4 tulips)

A farmer has two pieces of land in a parallelogram shape on the same base. He grows vegetables and flowers in two triangular pie

Hitman42 [59]

Step-by-step explanation:

In trapezoid ABCF, AB || CF.

Therefore, parallelograms ABEF & ABCD have same height and lie on the same base AB.

$\therefore Ar(\parallel^{gm} ABEF) = Ar(\parallel^{gm}ABCD)\\... (1)\\\\ \because\: Ar(\parallel^{gm} ABEF) \\=Ar(\triangle AFD) + Ar(\square \: ABED)....(2) \\\\\&\: Ar(\parallel^{gm}ABCD)\\= Ar(\triangle BCE) +Ar(\square ABED)....(3)$

From equations (1), (2) & (3), we find:

$Ar(\triangle AFD) + Ar(\square \: ABED) \\ = Ar(\triangle BCE) +Ar(\square ABED) \\ \\ \purple {\boxed {\therefore Ar(\triangle AFD) = Ar(\triangle BCE)}} \\$

Thus, the two triangular pieces of land are equal in area.

Hence proved.
