You ask 150 people about there pets.9/25 of the people have dogs.1/6 of the people who own a dog own a cat too. q1: how meany people own a cat and dog? q2: how meany own a dog explain?

150*9/25 = 1350/25 = 54

54 people own dogs

54*1/6 = 9

9 people own a dog and a cat

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!
