Hey there!
3^3 * x^2 - 25 / 5
= 3^3 * 0.6^2 - 25 / 5
= 3 * 3 * 3 * 0.6 * 0.6 - 25 / 5
= 9 * 3 * 0.6 * 0.6 - 25 / 5
= 27 * 0.36 - 25 / 5
= 9.72 - 25 / 5
= 9.72 - 5
= 4.72
Therefore, your answer is: 4.72
Good luck on your assignment & enjoy your day!

F(x) = x/2
g(x) = x - 3
f(8) = 8/2 = 4
g(f(x)) = 4 - 3 = 1
Answer g(f(8)) = 1

A) 84 : 120 --) 7 : 10, I came up with it by knowing x, # of times ordered,
7(x) : 3(x) sum will be 120 and guessed from there.
B) Well I came up with it trying to get the ratio for A, 84 smoothies.
C) 84 ( smoothies) - 36 ( juice drinks)

A) Ok you first have the birds from the first hour which sum up to 24. Then to calculate what of how many birds you saw for the second hour you use the ratio 2 (cardinals) : 3 ( chickadees) : 3 ( pigeons). Now before you use the ratio you need to know how many birds out of the 36 have not been seen in the first hour so just subtract 36 - 24 = 12. Next you figure out what number you can multiply every bird against to get a sum of 12 birds in total. I figured out it's 1.5 as a multiplier. I know physically it's not possible, but I did all the steps correct and apparently they don't care it's not realistic. I hope this helps you on the homework sheet.
Is the answer 5r-1? I'm not sure tho sorry if it's wrong!
Answer:
t=-4
Step-by-step explanation:
I know you don't care about any explanation, and just want the answer, but to get this, you can add 7 to both sides. Then you get -6t=24. Divide both sides by -6 and you get -4
