SOMEONE PLEAS11 Robert's new hybrid car has a gas tank that holds 12 gallons of gas. When the tank is full, they can drive 420 miles. Assume that their car uses gas at a steady rate.

a. What is the unit rate:

b. Write the equation:

c. Use your equation to find out how many gallons of gas Robert will need to drive 287 miles. 287miles =
gallons of gas

sorry i only know the answer of c

it's 8.2 gallons

Step-by-step explanation:

12 gallons = 420 miles

12 gallons = 420 miles? gallons =287 miles

420 miles ÷ 12 gallons = 35miles/gallon

420 miles ÷ 12 gallons = 35miles/gallon287 miles ÷ 35 miles/gallon = 8.2 gallons

Step-by-step explanation:

Unit rate = (420 miles)/(12 gallons) = (420/12 miles)/gallon = (35 miles)/gallon

Fuel consumption = (number of miles) × (1 gallon)/(35 miles)

287 miles × (1 gallon)/(35 miles) = 8.2 gallons

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺

probably the same as it is today since you did not eat the corn dogs yet
