Write an equation for the word problem: katie had a ribbon that was 23 ½ inches long. after katie cut the ribbon in two pieces, she had 8 ¼ inches of the ribbon left. how much ribbon did katie cut from her original ribbon?
a. 23 ½ - r = 8 ¼
b. 23½ + 8¼ = r
c. 23½ + r = 8¼
d. 8¼ - r = 23½

A is the answer.

Katie is starting with 23 ½ inches of ribbon and removing an unspecified amount, resulting in 8 ¼ inches left. When you remove one thing from a second thing, you are subtracting the first thing from the second. The equation then equals the amount that you have leftover.

I hope this helped!

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!

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
