The answer is x=6, y=9.

EXPLANATION

Segments QT and ST are congruent to each other because the diagonals meet at point T, which bisects them. Segments RT and PT are also congruent.

Deriving from this, we say

QT = ST
PT = RT

Choose one of these diagonals, so we can simply find one value of x we can substitute for another diagonal.

So, in this case, we use first PT = RT

PT = RT
2x = y+3
x=(y+3)/2

Now, we will plug in the value of x to the equation showing the congruence of segments QT = ST.

QT = ST
3x = 2y
3(y+3)/2 = 2y
3y+9/2 = 2y
(3y+9/2 = 2y)2
3y+9 = 4y
y = 9

Now, we have the value of y, substitute it to any of the two equations we had for the two diagonals.

2x = y+3
2x = 9+3
2x = 12
x = 6

There is a 12-ft fence on one side of a rectangular garden. The gardener has 44 ft of fencing to the enclose the other three sid
Morgarella [4.7K]

Answer:

  16 ft

Step-by-step explanation:

One of the other three sides is 12 ft. After that fence is subtracted from the total, there are 32 ft of fence left for the other two sides of the rectangle. That allows those sides to be 32 ft/2 = 16 ft long.

The rectangle can be 12 ft by 16 ft. The longer dimension is 16 ft.

2. 8x -28 = -140
8x -28 + 28 = -140 + 28
8x = -112
8x/8 = -112/8
x = -14

3. -9 + x/3 = -23
-9 + 9 + x/3 = -23 + 9
x/3 = -14
x/3/3 = -14/3
x = -14/3

4. x/-1.5 - 3.5 = -13.5
x/-1.5 - 3.5 + 3.5 = -13.5 + 3.5
x/1.5 = -10
x/-1.5/-1.5= -10/-1.5
x = 20/3

5.-6(x + 3) = -36
-6x - 18 = -36
-6x - 18 + 18 = -36 + 18
-6x = -18
-6x/-6 = -18/-6
x = 3

6. k + 3.7/9.8 = -0.22
k + 3.7/9.8/9.8 = -0.22/9.8
k + 3.7 = -2.156
k + 3.7 - 3.7 = -2.156 - 3.7
k = -5.856

7. 12(x - 6) = -108
12x - 72 = -108
12x - 72 + 72 = -108 + 72
12x = -36
12x/12 = -36/12
x = -3

8. -21.83x - -19.9 = -23.83
-21.83x + 19.9 = -23.83
-21.83x + 19.9 - 19.9 = -23.83 - 19.9
-21.83x = -43.73
-21.83x/-21.83 = -43.73/-21.83
x = 2

9. -10x - 68 + x = 40
-9x - 68 = 40
-9x -68 + 68 = 40 + 68
-9x = 108
-9x/-9 = 108/-9
x = -12

10. -34 - 3x - 2x = 71
-34 - 5x = 71
-34 + 34 - 5x = 71 + 34
-5x = 105
-5x/-5 = 105/-5
x = -21

11. 3x - 77 - 8x = 23
-5x - 77 = 23
-5x - 77 + 77 = 23 + 77
-5x = 100
-5x/-5 = 100/-5
x = -20

12. 3x - 5(2x - 12) = 123
3x - 10x + 60 = 123
-7x + 60 = 123
-7x + 60 - 60 = 123 - 60
-7x = 63
-7x/-7 = 63/-7
x = -9

13. -3x + 6(x + 6) = 15
-3x + 6x + 36 = 15
3x + 36 = 15
3x + 36 - 36 = 15 - 36
3x = -21
3x /3 = -21/3
x = -7

14. 5x + 2(4x - 9) = -174
5x + 8x - 18 = -174
13x - 18 = -174
13x - 18 + 18 = -174 + 18
13x = -156
13x/13 = -156/13
x = -12

15. -3x + 6(5x + 3) = -171
-3x + 30x + 18 = -171
27x + 18 = -171
27x + 18 - 18 = -171 - 18
27x = -189
27x/27 = -189/27
x = -7

Use the given information to answer the following questions. center (3, -9, 3), radius 5 (a) Find an equation of the sphere with
lianna [129]

Answer: The equation of the sphere with the center and radius

x^{2} +y^{2} +z^{2}-6 x+18 y-6 z+74=0

b) The intersection of this sphere with the y z-plane the x- co-ordinate

is zero(i.e., x = 0 )

Step-by-step explanation:

a) The equation of the sphere having center (h,k,l) and radius r is

(x-h)^{2} +(y-k)^2+(z-l)^2 = r^2

Given center of the sphere  (3, -9, 3) and radius 5

(x-3)^{2}+(y+9)^2+(z-3)^2 = 5^2

on simplification , we get solution

x^{2} -6 x+9+y^{2} +18 y+81+z^{2}-6 z+9=25

x^{2} +y^{2} +z^{2}-6 x+18 y-6 z+74=0

Final answer :-

x^{2} +y^{2} +z^{2}-6 x+18 y-6 z+74=0

b) The intersection of this sphere with the y z-plane the x- co-ordinate

is zero(i.e., x = 0 )

y^{2} +z^{2}+18 y-6 z+74=0
