Step-by-step explanation:

secants originating from the same point have the same relative length relationship :

outside part × sum of outside and inside parts

is the same for every secant from the same point.

so,

5×(7+5) = 6×(2x-8+6) = 12x - 12

60 = 12x - 12

12x = 72

x = 6

WV = 2x - 8 = 2×6 - 8 = 12 - 8 = 4

so, B is correct.

Please help ;-; Solve for the simultaneous equation…. 5x+y=17 X+y=3

Svetach [21]

Given Equation:-

5x+y=17 . . . . . . . . 1
x+y=3 . . . . . . . . . . 2

To find :

value of x
value of y

Solution :

Let's start with equation 2:-

x + y = 3

y = 3 - x

Put the value of y in Equation 1

5x+y=17
5x + (3 - x) = 17
5x - x + 3 = 17
4x + 3 = 17
4x = 17 - 3
4x = 14
x = 14/4
x = 7/2
x = 3.5

Now Let's find value of y:

put the value of x in equation 2:

y = 3 - x

y = 3 - 3.5

y = 0.5
