A partial solution to the equation [ax+b]=cx+d
line 1 [ax+b]= cx+d
line 2 -ax-b= cx+d
line 3 (-a-c)x= d+b
line 4 x= d+b/-a-c for x less than or equal to -b/a
the first error recorded is a. 1
b. 2
c. 3
d. 4

Regarding last question.
i never learnt that formula we have been using and for all other questions used 1 of two formulas sn=t1(r^n-1) / r-1 or sn=rtn-t1 / r-1
prev question
# 14 in the pre calculus textbook in Alberta
suppose a set of 10 beads were laid in a line where each successive bead had a diameter that was 3/4 of the diameter of the previous bead. If the first bead had a diameter of 24mm, determine the total length of the line of the beads. Express your answer to the nearest millimetre.

If I'm understanding this correctly you need to set up a sum series function:
$\sum_{x=0}^9=24mm\left(\frac{3}{4}\right)^x$∑x=09=24mm(34 )x
Note that the end of the series is 9, because for many series calculations the end of the series is (x-1).
Plug this formula into your calculator, or an excel sheet if you can, and you should get an answer of 90.59mm which makes the answer: Distance = 91mm.
