Answer:
18 miles
Step-by-step explanation:
You can start with the equivalence ...
1/2 in = 3 miles
and multiply it by 6.
6·(1/2 in) = 6·(3 miles)
3 in = 18 miles
Towns that are 3 inches apart on the map are 18 miles apart on the ground.
___
Why 6? because that is the number 1/2 needs to be multiplied by to get 3. Said another way, ...
3/(1/2) = 3·2 = 6
the answer is c: .... 72+8w
Let x represent the missing sides measurement.
x+x+28=52
combine like terms
2x + 28 = 52
subtract 28 from both sides
- 28 - 28
2x = 24
divide both sides by 2
x = 12
plug it back in
one leg is 12 inches
the other leg is 40 inches
