So find a common lets use 2 on the top
2x-4y=30
2x+4y=-18, now we have 4x=12, x=3
so lets substitute, lts use the top
3-2y=15
-2y=12
y=-6
im not sure x could be 12 i would try plugging each one them into the equation and see with one balances out
the other one is x=12, y=-3/2

IgorC [24]

Answer:

6 3/8

Step-by-step explanation:

Convert the fractions so that the denominators match.

$3\frac{3}{4} =3\frac{6}{8}$ , then $3\frac{6}{8}=\frac{30}{8}$

$1\frac{1}{8}=\frac{9}{8}$

$2\frac{1}{2}=\frac{3}{2}$ , then $\frac{3}{2}=\frac{12}{8}$

Add up the fractions.

$\frac{30}{8}+\frac{9}{8}+\frac{12}{8} =\frac{51}{8} =6\frac{3}{8}$

Light shines through window what is the area of a trapezoid shaped region created by the light

bogdanovich [222]

Answer:

16 ft²

Step-by-step explanation:

The complete question is attached.

A trapezoid is a quadrilateral (has four sides) with one a parallel base. The base angles and the diagonals of an isosceles trapezoid are equal.

The area of a trapezoid = [(sum of the parallel bases) / 2] * height of the trapezoid.

Given that the parallel bases are 3 ft and 5 ft, while the height of the trapezoid is 4 ft. Hence:

The area of a trapezoid = [(3 + 5)/2] * 4

The area of a trapezoid = 16 ft²
