Given that
5x:9=7:3
Calculate the value of
x

Step-by-step explanation:

4.2

Step-by-step explanation:

5x:9=7:3

5x/9=7/3

5X×3=7×9

15x=63

X=63/15

X=4.2

So the value of the X is 4.2

is there supposed to be a diagram or a graph for this one? ?

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
