Step-by-step explanation:
Equation:√9a^2+√49b-a+√b
=3a+7√b-a+√b
=3a-a+7√b+√b

There's a lot of different kinds. But they're all pretty simple and can be explained rather easy.
A ratio and a proportion are really the same thing but in different ways. For example, say I have two lines. A big line and a small line. The big line is 10 feet tall, and the little line is 5 feet tall. We can say they are proportionate to each other because they have a ratio of 10/5 which can be simplified to 2.They are proportionate and the taller line is 2 times higher.
I hope this makes sense.

Answer:
70% in favor of building a new playground
<em>3500 (</em><em>in favor</em><em>) + 1500 (</em><em>against it</em><em>) = 5000 (</em><em>total number votes</em><em>)</em>
<em />
<em>3500 (</em><em>in favor</em><em>) 1500 (</em><em>against it</em><em>)</em>
<em> ------------------- = 0.7 / 70% ------------------- =0.3 / 30%</em>
<em>5000 (</em><em>total</em><em>) 5000 (</em><em>total</em><em>) </em>
