Mattie’s house consists of two stories and an attic. the first floor is 8 5/6 feet tall, the second floor is 8 1/2 feet tall, and the entities house is 24 1/3 feet tall. how tall is the attic?

The attic is 7 feet tall.

Step-by-step explanation:

8 5/6 + 8 1/2 = 53/6 + 17/2 = 53/6 + 51/6 = 104/6

24 1/3 - 104/6 = 73/3 - 104/6 = 146/6 - 104/6 = 42/6 = 7 Feet tall

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!
