<span><span>2x(x - 5) + 3(x - 5) (rewriting expression)
</span><span>2x(x) - 2x(5) + 3(x) - 3(5) (applying distributive property)
</span><span>2x^2 - 10x + 3x - 15 (simplifying)
</span><span>2x^2 - 7x - 15 (combining like terms)
I found this as an example from research. I do hope this helps. I have trouble in the same subject or I used to anyway. I hope this is what you were looking for. :)</span></span>
20:30 so it becomes 2:3 as a fraction it would be 2/3. a fraction is basically a ratio.
We plug in -10 as x and 6 as y. We get -30 - 60 - 24 = -90 - 24 = -114

Hope this helps!

10x-9=9x
-9=-x
x=9
angle 7 = 9*(9)=81
angle 6 = 180-81= 99
