0.2B+0.1S=C0, point, 2, B, plus, 0, point, 1, S, equals, C Rhia is using the above equation to investigate the carbon footprint, CCC, in kilograms of carbon dioxide (CO_2)(CO 2 )left parenthesis, C, O, start subscript, 2, end subscript, right parenthesis emissions, for her morning commute, during which SSS miles are by subway and BBB miles are by bus. How many kilograms of CO_2CO 2 C, O, start subscript, 2, end subscript per mile does the bus portion contribute to Rhia's carbon footprint?

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

a

explanation:

x+14

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!
