Solve: 6-t/2t+9 = -2

dangina [55]

<span>6-t/2t+9 = -2
multiply both sides by 2t+9
which will give you
6-t= -2(2t+9)
6-t = -4t + 18
now add 4t to both sides
6 -t + 4t = -4t -18 + 4t
6 + 3t = -18
6-6 + 3t = -18 -6
3t = -24
t = -24/3
t= -8 (negative 8)

Anja divides (8x3 – 36x2 + 54x – 27) by (2x – 3) as shown below. What error does Anja make

love history [14]

Answer:

54x - 75 / 2x - 3

Step-by-step explanation:

8 * 3 - 36 * 2 + 54x - 27 / 2x -3

you will need to multiply 8 with 3, and 36 with 2

which will give you 24 and 72

24 - 72 + 54x - 27 / 2x - 3

then up common terms together but they cant change places as in the numbers in the numerators stay with the other numbers in the numerator

54x - 75 / 2x - 3
