Which equation describes this relationship?

its the first one

Step-by-step explanation:

because you just leave the t alone and bring down the 5 and you get t=5g then since you have to pay 20 your taking away money and using it to pay that bill and therefor it makes it minus and your equation will be t=5g-20 hope this helps :)

the answer to this question is 3/19

step-by-step explanation:

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!
