The distance from the library to the post office is 5.25 miles. use the fact that one mile is approximately 1.61 kilometers to find the distance from the library to the post office in kilometers. round the distance to the nearest hundredth of a kilometer, if needed.

8.45 kilometers

Step-by-step explanation:

Given

The distance from library to post office = 5.25 miles

We are given that one mile is equal to 1.61 kilometers

So to find the distance from the library to post office in kilometers we have to multiply 5.25 with 1.61

So,

The distance from library to post office in kilometers = 5.25*1.61

8.4525

Rounding off to nearest hundredth

8.45 kilometers ..

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
