(4ab - 8a 2 + 12ac) ÷ 4a

ioda

we are given

$\frac{(4ab-8a^2+12ac)}{4a}$

we can see that

4a is in multiple in numerator

so, we can factor it out

$\frac{4a(b-2a+3c)}{4a}$

now, we can cancel 4a

and we get

$(b-2a+3c)$ .............Answer

29. Martin has some dollar notes. 20% of the notes are $10 notes, 40% of

Katena32 [7]

Answer:

225 notes

Step-by-step explanation:

Let the number of notes is x.

20% of notes is:

0.2x

40% of the remainder is:

40% of 0.8x, so it is
0.8x*0.4 =
0.32x

Remaining notes are:

x - 0.2x - 0.32x =
0.48x

Total of the notes:

0.2x*10 + 0.32x*5 + 0.48x*2 = 1026
2x + 1.6x + 0.96x = 1026
4.56x = 1026
x = 1026/4.56
x = 225
