Cuántas de esas personas eran niños? \( \begin{array}{lll}\text { (A) entre } 25 \text { y } 35 & \text { (B) entre } 35 \text { y } 45 & \text { (C) entre } 45 \text { y } 55 \\ \text { (D) entre } 55 \text { y } 65 & \text { (E) entre } 65 \text { y } 75 & \end{array} \)

which of the following equations is not a linear function? 1) \( 2 y-3 x=1 \) 2) \( 4 x^{2}+y^{2}=4 x y \) 3) \( y=2 \) 4) \( x=2 \)

3. Question 3. Solve \( x-5=3 x+2 \)

\( \equiv \) (i) Listen A bowl contains blueberries and strawberries. There are a total of 12 berries in the bowl. The ratio of blueberries to strawberries is 1 to 2 . How many of each berry are in the bowl? \( \square \) blueberries strawberries

Add \( 5 \mathrm{a}-3 \mathrm{~b} \) and \( -5 \mathrm{~b}+3 \mathrm{a} \) the result is ...... \[ \begin{array}{l}8 \mathrm{a}-8 \mathrm{~b} \\ 8 \mathrm{a}+8 \mathrm{~b} \\ 8 \mathrm{~b}-8 \mathrm{a} \\ 2 \mathrm{a}-2 \mathrm{~b}\end{array} \]

Three consecutive numbers their sum is 48 write an equation express that is .... \( \begin{array}{l}3 x+2=48 \\ 3 x+4=48 \\ 3 x+3=48 \\ 3 x-3=48\end{array} \)
