Answer:
x=9
Step-by-step explanation:
I took one side, and made proportions:
12:16
3:4
so, x-1:6=3:4
(x-1)/6=3/4
solve it for x=9
3 units because 3 is on the x axis
The answer is 4.782, so yes maria is correct:-)
When dividing, you can flip the second fraction and multiply the two, giving you 5x/9 * 15x^2/18, which is 25x^3/54
