Every hour of driving uses up to 3 gallons of gas. use a table to find how many gallons of gas would be used in 15 hours. is the answer 45 gallons?

45 gallons of gas is used for 15 hours.

Step-by-step explanation:

As given

Every hour of driving uses up to 3 gallons of gas.

i.e

1 hour = 3 gallons of gas.

Now calculated gallons of gas used for 15 hours .

Gallons of gas used for 15 hours = 15 × Gallons of gas used for 1 hours.

Putting the values in the above

Gallons of gas used for 15 hours = 15 × 3

                                                       = 45

Therefore the 45 gallons of gas is used for 15 hours.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
