Answer:

- 120

Step-by-step explanation:

call x is the number you want to find

  1. (3/4 )x + 3\frac{1}{2} = (2/3)x - 6\frac{1}{2}
  2. (3/4)x + (7/2) = (2/3)x - (13/2)
  3. (3/4)x - (2/3)x = - (13 /2) - (7/2)
  4. (1/12)x = -10
  5. x = -10 / (1/12) = -120

Sliva [168]

Answer:

( x+1)^2  + (y+2)^2 = 25

The center is (-1, -2) and the radius is 5

Step-by-step explanation:

x^2 + 2x + y^2 + 4y = 20

Complete the square

2/2 =1  1^2 =1  so add 1 for x     4/2 =2  2^2 = 4 so add 4 for y

x^2 +2x +1   +y^2 +4y+4 = 20 +1 +4

( x+1)^2  + (y+2)^2 = 25

(x+1) ^2 + (y+2)^2 = 5^2

(x - -1) ^2 + (y -  -2)^2 = 5^2

This is in (x-h)^2 + (y-k)^2 = r^2 form where (h,k) is the center and r is the radius

The center is (-1, -2) and the radius is 5

The measures of two complementary angles have a ratio of 3:2 what is the meusure of the larger angle
ozzi

Answer:

54

Step-by-step explanation:

The two angles add to 90 degrees since they are complementary

the ratio is 3:2

Multiply by x

3x:2x

Add them together and set equal to 90

3x+2x=90

5x=90

Divide each side by 5

5x/5 = 90/5

x = 18

The first angle is 3*18 = 54

The second angle is 2*18 = 36
