First distribute -8(6+5n) that would be -48+-40n so 3n-5= -48-40n you want the n's on one side so add 40n to the 3n which is 43n+5=-40 than subtracts 5 from each side and it leaves u with 43n=-45 than u divide
Answer:
6 and 9
Step-by-step explanation:
6 x 9 = 54
Answer:
a. The Mexican Airline offers a better deal for 9 students to travel.
b. 10 students
Step-by-step explanation:
a. The Mexican Air airline offers a round trip airfare of $250 per person.
So, for 9 students the fare will be total $(250 × 9) = $2250
Now, the Fiesta airline offers a round trip airfare of $150 per person if the club agrees to pay a one-time group rate processing fee of $1000.
So, for 9 students the total fare will be = $[1000 + (150 × 9)] =$2350.
Therefore, the Mexican Airline offers a better deal for 9 students to travel. (Answer)
b. Let for x students both the airline offers the same total costs.
Then we can write
250x = 1000 + 150x {From the conditions given}
⇒ 100x = 1000
⇒ x = 10
So, if the number of students is 10, then only both the airlines will take same fare. (Answer)
-4(-1.5 - 9)
-4 x -1.5 = 6
-4 x 9 = -36
Answer is -30
(x+1)(2x+1)(x-2)
= (2x+1)(x+1)(x-2)
= (2x+1)(x² -x - 2)
= 2x³ - 2x² - 4x + x^2 - x - 2
= 2x³ - x² - 5x - 2
Answer: 2x³ - x² - 5x - 2
