A scale on a map shows that 2 inches = 25 miles.

Simora [160]

A:
2 inches - 25 miles
x inches - 60 miles

Set up a proportion:
$\frac{2}{25} = \frac{x}{60} \\ \\
\frac{2}{25} \times 60=x \\ \\
\frac{120}{25}=x \\ \\
x=4.8$

4.8 inches on the map represent 60 miles.

B:
2 inches - 25 miles
1/4 inches - x miles

Set up a proportion:
$\frac{2}{25}=\frac{\frac{1}{4}}{x} \\ \\
\frac{2}{25}x=\frac{1}{4} \\ \\
x=\frac{1}{4} \times \frac{25}{2} \\ \\
x=\frac{25}{8} \\ \\
x=3.125$

3.125 miles are represented by 1/4 inches on the map.

1. Keith bought 6 baseball cards. His dog ate half of his collection and he was left with 36 cards. How many did he start with?

Alenkinab [10]

1. Answer=66cards

Lets use the variable 'x' to represent the number of baseball cards in Keith's collection that he started with. The following equation can be made.

(x+6)/2=36
multiply both sides by 2
x+6=72
subtract 6 from both sides
x=66 cards

2. Answer=$12

Lets use the variable 'a' to represent Sara's allowance. The following equation can be made:

(a/2)+7=13
subtract 7 from both sides
a/2=6
multiply both sides by 2
a=$12
