The perimeter of a rectangular garden is 510 ft. The two short sides of the garden are each 25 ft. long. You are asked to find the length of the other sides. Which equation models this situation? A.25 +$10
B. 25 + 2x 510
C. 25(x - 2) = 510
D. 2(25)+ 2x - 510

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!

that would be a prism, if not right, feel free to correct me
