On a map, the scale is 5 inch= 200 miles. Find the actual distance (mi) between two stores that are 10 inches apart on a the map
Goryan [66]
Answer:
Try and find it yourself

Explanation:
Set up a ratio: 200/1 = x/4.5 (x = actual distance in miles)
4.5 * 200 = x (multiply both sides by 4.5)
x = 900 miles. And that makes logical sense if you look at it: for every 200 miles you have 1" on the map. So for 4.5" you now have 900 miles. You can also have other ratios, such as x/200 = 4.5/1

Lee is 19 years old, and Amira is 16 years younger. In how many years will Lee be three times as old as Amira?
Tasya [4]

Answer:

in 5 years

Step-by-step explanation:

If Lee is 19 and Amira is 16 years younger, Amira is:

19-16 = 3 years old

So, we need to find how much time in years will pass until Lee's age is three times Amira's. Lets call x the number of years until this happens. So, in x years from now Lee will have 19+x years old, and Amira will be 3+x years old. And this ages must be such that Lees age is 3 tamis Amira's. Thus:

19+x = 3(3+x)

19 + x = 9 + 3x

Subtract 9 in both sides:

19-9 + x = 9 -9  + 3x

10 +x = 3x

Subtract x in both sides:

10 + x -x = 3x -x

10 = 2x

Divide both sides by 2

10/2 = 2x/2

5 = x

So, in 5 years Lee will have three times the age of Amira. Lets verify.

Lee will hace 19+5=24 years old

Amira will have 3+5=8 years old

24/8 = 3

So, its verified!
