Answer:
3:2
Step-by-step explanation:
I'd say 3:2 because when you divide 45/30, you get 3/2, which is the same as 3:2. Hope this helps!
7^2 - 3 + 9 x 8 / 2
49 - 3 + 9 x 8 / 2
49 - 3 + 72/2
49 - 3 + 36
46 + 36
82
w = 82
<span>9x-4=7-2x <em>/+2x
</em><em />11x-4=7 <em>/+4
</em><em />11x=11 <em>/:11
</em>x=1<em>
</em><em /><em /></span>
This problem is tough until you clean it up so you can see what's going on.
On the left side, (7 + 5 - 3) = 9 . So the left side is x + 9 .
On the right side, (16 - 8) = 8.
So the equation is really <u>x + 9 = 8</u>
Subtract 9 from each side: <em> x = -1</em>

By, Cross multiplying, we get



Here,
