The time it takes to wash all the windows on a large building w(x) varies inversely with the number of workers assigned to the job x. it takes 6 hours to complete the job when 4 workers are assigned to it. which equation can be used to find the time to complete the job when x workers are assigned to it? a. w(x) = 1.5x b. w(x) = 24x c. w(x) = 10/x d. w(x) = 24/x

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!
