Martin runs 100 meters in 15 seconds. what is the equation for d, the distance in meters that martin covers per second? a.15 + d = 100 b.100 + d = 15 c. d × 15 = 100 d. d × 100 = 15 anyone know the answer i need this because so i can get good gifts for my birthday its on march 30 so plz dont just say hi give me a answer pl. you

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!
