I am pretty sure it would be $4.10 per gallon. I hope this got to you in time.
If d = rt, Then r = d/t
avg speed = 720/t
Therefore after subtracting penalty points, the function for score is:
For part 2 i will attach a picture.
Part 3)
Set s = 3 and solve for t
Here, every term is -2 times than it's previous term. so,
5th term = 8 * -2 = -16
So, -16 is your answer.
Hope it helped.
Answer:
x=-32/11
Step-by-step explanation:
Let's solve your equation step-by-step.
1/(x+3)=11
(1/n=reciprocal of n)
Step 1: Multiply both sides by x+3.
1=11x+33
11x+33=1(Flip the equation)
11x+33−33=1−33(Subtract 33 from both sides)
11x=−32
11x/11=−32/11
(Divide both sides by 11)
x=−32/11
Check answers. (Plug them in to make sure they work.)
x=−32/11
(Works in original equation)
