<h3>Answer:</h3>

[5] <u>By central angle property</u>,

  • x = 6x - 290
  • x - 6x = - 290
  • - 5x = - 290
  • x = 290/5
  • x = 58.

[6] <u>By same arc property</u>,

  • 8x + 4 = 9x - 11
  • 8x - 9x = - 11 - 4
  • - x = - 15
  • x = 15.

[7] <u>By central angle property</u>,

  • 7x + 4 = 2x + 49
  • 7x - 2x = 49 - 4
  • 5x = 45
  • x = 45/5 = 9.

[8] <u>As they are radius i.e, equal</u>,

  • x + 9 = 2x + 6
  • x - 2x = 6 - 9
  • - x = - 3
  • x = 3.

[9] <u>By central angle property</u>,

  • 9x = 12x - 21
  • 9x - 12x = - 21
  • - 3x = - 21
  • x = - 21/- 3
  • x = 7.

[10] <u>They are radius so equal</u>,

  • 8x + 2 = 10x - 20
  • 8x - 10x = - 20 - 2
  • - 2x = - 22
  • x = -22/-2
  • x = 11.

The total cost of 4 goldfish and 3 guppies is $29. 3 goldfish and 5 guppoes cost $30. How much does each cost
Aneli [31]

let the goldfish be x and the guppies be y

4x + 3y = 29...equ(1)

3x + 5y = 30...equ(2)

multiplying equation 1 by 5 and equation 2 by 3

20x + 15y = 145...equ(1)

9x + 15y = 90...equ(2)

subtracting equation 2 from 1

11x = 55

∴x = 5

 substituting the value of x into equation

4(5) + 3y = 29

20 + 3y = 29

3y = 9

∴y =3

What number "c" completes the square: x^2 - 14x + c
Vladimir79 [104]

Answer:

49

Step-by-step explanation:

To complete the square we use the formula:

c=(\frac{b}{2} )^{2}

So we can plug in 14 for b to find c.

c=(\frac{14}{2} )^{2}\\\\c=(7 )^{2}\\c=49

Now this equation can be factored into:

(x-7)^{2}

I WILL MARK BRAINLIEST! Solve for X
NARA [144]

Answer:

Step-by-step explanation:

You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional.  So set up two ratios that are = to each other

On the left

long side small triange / long side large triangle = base small triangle / base large triangle

On the right

hypotenuse/longest leg = hypotenuse / longest leg.

Problem A

Set up the similar Proportion

5/40 = x/20                Cross Multiply

40x = 20*5

40x = 100                   Divide by 40

x = 100/40

x = 2.5

Problem B

Again set up the similar triangle proportion

15/10 = x/2                  Multiply by 2

15*2/10 = x              

3 = x
