Arnie skated 1 3/4 miles from home to the lake. he stated 1 1/3 miles around the lake and then skate it back home. how many miles to the he skate in all?

miles.

Step-by-step explanation:

We have been given that Arnie skated 1 3/4 miles from home to the lake. He skated 1 1/3 miles around the lake and then skate it back home.

To find the total miles that Arnie skate in all we will add all distances covered by Arnie while skating.

Upon converting our mixed fractions into improper fractions we will get,

Now let us have a common denominator,

Therefore, Arnie skated miles in all.

3

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!

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
