Answer:

x = 23

Step-by-step explanation:

3x + 50 = 6x - 19 (Vertically Opposite Angles)

=> 6x - 19 = 3x + 50

=> 6x - 3x = 50 + 19

=> 3x = 69

=> x = 69/3

=> x = 23

A parking lot has spaces reserved for motocyles, cars and vans. There are five more spaces reserved for vans than motorcycles. T

77julia77 [94]

Answer:

motorcycles: 20
vans: 25
cars: 135

Step-by-step explanation:

There are 3 car spaces for each non-car space, so the number of car spaces is 3/4 of the total: (3/4)×180 = 135.

The number of motorcycle spaces is half of 5 less than the remainder, so is ...

(180 -135-5)/2 = 20

and van spaces are 5 more than that: 25.

There are 20 motorcycle spaces, 25 van spaces, and 135 car spaces.

Mia found the area of a polygon The area is 32 square cm.

solniwko [45]

Answer:

Only the isosceles trapezoid has an area of 32 cm².

Step-by-step explanation:

Let's calculate the area of each polygon.

For the two triangles we have:

$A_{t} = \frac{bh}{2} = \frac{2 cm*4 cm}{2} = 4 cm^{2}$

This polygon does not have an area of 32 cm².

For the rectangle we have:

$A_{r} = bh = 6 cm*4 cm = 24 cm^{2}$

This polygon does not have an area of 32 cm².

For the rectangle trapezoid we have:

$A_{rt} = A_{t} + A_{r} = (4 + 24) cm^{2} = 28 cm^{2}$

So, this polygon does not have an area of 32 cm².

Finally, for the isosceles trapezoid:

$A_{it} = A_{t}*2 + A_{r} = (4*2 + 24) cm^{2} = 32 cm^{2}$

This polygon does have an area of 32 cm².

Therefore, only the isosceles trapezoid has an area of 32 cm².

I hope it helps you!
