Answer:
D 36
Step-by-step explanation:
<em>Write the information algebraically</em>
c = 3a
c + a = 48
c = children, a = adults
<em>In the second sentence (in bold), we can replace c with 3a</em>
c + a = 48 → 3a + a = 48
<em>Simplify</em>
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
<em>We can then substitute or plug in a = 12 into the original equation:</em>
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)
<h3>There are 36 children</h3>

Answer:
2.875 mi
Step-by-step explanation:
A scale factor (SF) is the ratio of two corresponding lengths in similar figures.
SF = actual distance/map distance = 5.75 mi/2 in
or 1 in = 2.875 mi
On the map, the distance from the library to the park is 1 in, so the actual distance is 2.875 mi.
