6(3x+5)
6*3x=18x
6*5=30
<u>18x+30</u> is your answer! I hope this helped! :)
Answer: Linear model
and H'(t) = 9 units.
Step-by-step explanation:
Since we have given that
In 2000, amount spent = $100 billions
In 2010, amount spent = $190 billions.
So, rate of increase would be

So, linear model for H(t) would be

So, H'(t) would be 9.
Hence, linear model
and H'(t) = 9 units.
With constant speed it will take her : 405 ml / 45= 9 hours of drive
Answer:
Step-by-step explanation:
y = total cost of gas
x = gallons of gas
(a)
y = 1.60x
(b)
y = 1.60x
32.00 = 1.60x
32.00 / 1.60 = 1.60x / 1.60
32.00 / 1.60 = x
20 = x
x = 20
Trevor bought 20 gallons of gas.
