Find z for the following proportion:<br><br><br> z/9= 2/3

serg [7]

Cross multiplication will help find the value of x
$\frac{z}{9} = \frac{2}{3} 


$
9*2=18
3*z=3z

Now we have :
3z=18
Divide both sides by 3 to isolate z

Final answer: z=6

So you know:
1) There are 180° in a triangle.
2) A straight line is also 180°.
So the three angles in the triangle are
2x, 103-x, and (180-(6x-7)).
Solve for x!
2x + 103-x + (180-(6x-7)) = 180
2x + 103-x + 180-6x+7 = 180
-5x = -110
x = 22

Consider the quadratic equation below. 4x^2-5=3x+4 Determine the correct set-up for solving the equation using the quadratic for

Kipish [7]

4x²-5=3x+4
4x²-3x-9=0

x=(3±√((-3)²-4*4*-9))/2*4

x=3±√(9+144) /8

x=(3±√153) /8

x=⅜±√153/8
