Math solve for x pls
olchik [2.2K]

Answer:

26

Step-by-step explanation:

Plug in 15 for y in the first problem so instead of y=x-11 it would be 15=x-11

15=x-11

+11= +11 (you want to add 11 to both sides to get x by its self)

26=x

In kite ABCD, AB = BC and CD = DA. AB = (3x + 4), BC = x + 8, CD = y + 7, and DA = 2y + 5, find the perimeter of the kite
lana [24]
3x + 4 = x+ 8   >  3x - x = 2x   >  2x + 4 = 8 >  8 - 4 = 4 > 2x / 2 crosses out > 4 / 2 = 2 > x=2
2y + 5 = y + 7 >  2y - y = y >  y+ 5 = 7 >  7-5= 2 > y=2 
 
the perimeter of the kite is 4

If y varies directly with x and y=2 when x=15. Find x when y=8.
andreyandreev [35.5K]
Since the two numbers vary directly, if Y is quadrupled, X will do the same.  2 times 4 is 8, 15 times 4 is 60.

X = 60.

Hope that helps!! :)

AB= 4x + 7 and BC = 20x - 5 <br> AB ~= BC
Mariana [72]

The value of the variable x is 3/4

<h3>What are congruent segments</h3>

Congruent segment are segments with equal or congruent lengths.

From the information given, we have that line AB is approximately equal to line BC. This is represented as;

AB = BC

Where;

  • AB = 4x + 7
  • BC = 20x - 7

Now, let's equate the expressions

4x + 7 = 20x - 5

collect like terms

4x - 20x = - 5 - 7

- 16x = - 12

Make 'x' the subject of formula

x = -12/-16

x = 3/4

Thus, the value of the variable x is 3/4
