In his den, Matt wants to build two shelves. One shelf is to measure four and three over4 3/4 feet long and the other five and 5 5/12 feet long. Is a board 11 feet long enough for both shelves

10¹/₆ feet is less than 11 feet board, it's enough for both shelves

Step-by-step explanation:

First shelf is to measure = 4³/₄ feet

Second shelf is to measure = 5⁵/₁₂ feet

Total length of available board = 11 feet

Hence length of 1st and 2nd shelves are added to determine if its less than or equal to 11 feet

Length of 1st and 2nd shelves = 4³/₄ + 5⁵/₁₂ = 122/12 feet = 10¹/₆ feet

10¹/₆ feet is less than 11 feet board, it's enough for both shelves

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!
