Hey there!
(8f - 9) - (9f - 6)
= 8f - 9 - 9f + 6
= 8f - 9f - 9 + 6
= -f - 3.
Steps :-
Remove the brackets.Bring the like terms together.Simplify the equation.Hope it helps ya!
Answer:
-1 ( f +3) or -f - 3
Step-by-step explanation:
( 8f - 9 ) - ( 9f - 6 )
Add like terms:
8f - 9f = -1f = -f
-9 - -6 = -3
-f - 3
simplify:
-1 ( f +3)

Step-by-step explanation:
A scrapyard had 200 tons of recycled steel. They sold 15 tons per day for several days. If there are 80 tons left at the scrapyard, how many days have passed?
a) Write and solve an equation to answer the question.
b) What does the solution of your equation mean in terms of the answer to the question?
Answer:
A.
200 - 80 = 120
120 / 15 = 8
8 days passed

On a round trip over the same roads, Sophia averaged 24 mi/hr going and 30 mi/hr coming back. If the whole trip took 13.5 hours, what is the distance one way? (Hint: Find the time for each part of the round trip)
Answer:
d = rt. In this problem we are looking for the distance, but we will have to go about it indirectly. If she's traveling the same exact road going and returning, then the distance traveled both ways is exactly the same. Since d = rt, and d is the same, by the substitution property, if and , then , and . So we need to rt for the trip going, rt for the trip returning and set them equal to each other and solve for t. Going is a rate of 24, and the time is t (since we don't know t), and returning is a rate of 30, and the time is 13 1/3-t. (If the whole trip takes 13 1/3 hours, and t is the time going, then the time returning is the difference between the total time and the going time. That concept is one that baffles most algebra students!). So our r1t1 is 24t, and our r2t2 is 30(13 1/3 - t). Set them equal to each other and that will look like this: That fraction of 40/3 is 13 1/3 made into an improper fraction. Distributing that we will have and 54t = 400. That means that t = 7.407. We have time, and that's great, but we need distance! Go back to one of your equations for distance and sub in t and solve for d. d = 24t, and d = 24(7.407), so d = 177.768 miles.

To avoid a storm, a passenger-jet pilot descended 0.38 mile in 0.4 minute. What was the plane's average change of altitude per minute?
Answer:
0.55 mile / minute
Step-by-step explanation:
The average change of altitude per minute would simply be the ratio of distance descended over time. That is:
average change of altitude = distance / time
average change of altitude = 0.44 mile / 0.8 minutes
average change of altitude = 0.55 mile / minute

Answer:
From least to greatest: {3/10 + 3/8}, {3/10 + 3/4}, {1 2/15 + 1/10}, {1 2/15 + 3/8}
Step-by-step explanation:
Simplify each expression:
1 2/15 + 1/10 = 17/15 + 1/10: The LCM is 30 because 15 × 2 is 30 and 10 × 3 = 30. So multiply 17/15 by 2 so you get 34/30. Then multiply 1/10 by 3 to get 3/30. So you get 34/30 + 3/30 = 37/30.
3/10 + 3/4: The LCM is 20 because 10 × 2 = 20 and 4 × 5 is 20. So multiply 3/10 by 2 so you get 6/20. Then multiply 3/4 by 5 so you get 15/20. So you get 6/20 + 15/20 = 21/20.
1 2/15 + 3/4 = 17/15 + 3/4: The LCM is 60 because 15 × 4 = 60 and 4 × 15 = 60. So multiply 17/15 by 4 to get 68/60. Then multiply 3/4 by 15 so you get 45/60. So you get 68/60 + 45/60 = 113/60.
3/10 + 3/8: The LCM is 40 because 10 × 4 = 40 and 8 × 5 = 40. So multiply 3/10 by 4 to get 12/40. Then 3/8 by 5 to get 15/40. So you get 12/40 + 15/40 = 27/40.
Now you have: 37/30, 21/20, 113/60, 27/40. Now you can use a calculator evaluate each quotient and determine the order of each expression.

please give me a brainliest answer
Answer:
x = 26/3 or 8.6666...
Step-by-step explanation:
-1/5(15x-10)= -24-1/5×15x+-1/5×(-10) = -24-3x+2 = -24-3x = -24-2x = -26/-3x = 26/3Tank A has a capacity of 20 L. It is half
