he cost of 20 chocolates is Rs 360 , what will be the cost of one dozen abought a dozen banana of Rs 96 , what will be the cost if she will add 6 mi anas in it?

b) \( \frac{\sqrt{1,3}\left(\frac{5}{4}+\frac{1}{3}\right)}{\left(\frac{6}{5}\right)^{-1}}=\frac{2 x-0,4}{x+1,2} \)

Los matrisekvationen \( \operatorname{sar} \quad A=\left(\begin{array}{ccc}1 & 0 & 2 \\ -2 & 1 & 0 \\ 0 & 1 & 1\end{array}\right) \quad \) och \( B=\left(\begin{array}{ccc}1 & 3 & 0 \\ -1 & -2 & 0 \\ 0 & -1 & -1\end{array}\right) \)

B is the midpoint of segment AD. C is the midpoint of segment BD. located at \( (-1,-6) \) and \( D \) is located at \( (3,0) \). What are the coordinate: Draw and label a picture to help. ( \( -1,3) \) \( O(2,-1.5) \) \( O(-3,1) \) \( O(-4,3) \)

f) \( y=\log _{8}(x)-2 \)

\( f(x)=-2 x+3 \) en \( x=-1 \)
