A carpenter is making one shelf that is 37.5 cm long and another that is 54.7 cm
long. How much wood does she need?

93 cm of wood

Step-by-step explanation:

when you add them together you get 92.2 cm long so I would guest you round it up to 93 cm long

let me know if i'm wrong

you add 37.5+54.7 =91.4

37.7

54.7

  9  1. 4

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

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!
