Does someone mind helping me with this question? Thank you!

Answer:

160 sq cm

Step-by-step explanation:

Since the two trapezoids are similar, you can use a ratio to find the area.

If we use x to represent the area of ABCD, then the ratio will look something like:

5/20 = 40/x

which then we can solve x to be 160 sq cm.

Uhh help lol<br> 5.3x + y = 28.5 <br> 4.2x + 3.1y = 27.2<br> find x and y

navik [9.2K]

Answer:

x = 5, y = 2

Step-by-step explanation:

First, isolate y in the top equation.

$y = -5.3x+28.5$

Next, substitute y in the bottom equation.

$4.2x + 3.1(-5.3x + 28.5) = 27.2$

$5.3x + y = 28.5$

Simplify.

$4.2x + -16.43x + 88.35 = 27.2$

Combine like terms.

$-12.23x + 88.35 = 27.2$

Isolate x on one side.

$-12.23x = -61.15$

Isolate x.

$x = 5$

Substitute x into $5.3x + y = 28.5$

$5.3(5) + y = 28.5$

Simplify.

$26.5 + y = 28.5$

Isolate y.

$y = 2$

$x = 5 \\y = 2$
