Answer:

x = 3

Step-by-step explanation:

In a parallelogram, opposite sides have the same length. Then:

segment DC = segment AB

and

segment DA = segment CB

Replacing with data from the picture, we get:

18*x - 5 = 15*x + 4

18*x - 15*x = 4 + 5

3*x = 9

x = 9/3

x = 3

Which measure is less than 435 inches
devlian [24]
12 ft 3 in

37 x 12 = 444 in
36 x 12 = 432 
  432+10= 442
12 x 3 = 36 
   36 x 12 = 432 
   432 + 3 = 435
12 x 12 = 144 
   144 + 3 = 174

Need help! Will mark u brainliest for the right answer!
kirill115 [55]

To find the perimeter of this blue figure, add together the shown lengths of the six sides.  

The three measurements on the top have the LCD 4, so we combine 14 3/4, 4 2/4 and 8 2/4.  The sum is 26 7/4, or 27 3/4, or 27.75.

The three measurements on the bottom share the LCD 5, so we can immediately combine them, obtaining 32 8/5, or 33 3/5, or 33.60.

Combining 27.75 and 33.60 results in 61.35, or 61 35/100, or 61 7/20.

The perimeter of the given figure is 61 7/20.

What is the center and radius of the following circle: x2 + (y _ 6)_ = 50
Rama09 [41]
The true question should be like this:
<span>What is the center and radius of the following circle: x^2 + (y _ 6)^2 = 50, 
circle quation formula is (x-a)^2 + (y-b)^2 = R², so by identifying each term, we find </span>(x-a)^2=x^2 = (x-0)^2, (y-b)^2= (y _ 6)^2, R² = 50, implies R =5sqrt(2), 
it is easy to identify that the center is (a,b)= (0, 6)
the radius is R =5sqrt(2),
