4. Kiana has two hours to complete her homework after school. She needs to complete an assignment for Spanish and an assignment for biology. Kiana sets up an inequality to represent the length of time in minutes she spends on Spanish, \( s \), and biology, \( b \), including the constraints. What is the correct inequality? \( 0 \geq s+b<120 \) \( 120 \leq s+b \) \( 0 \leq s+b \) \( 0 \leq s+b \leq 120 \)

\( \equiv \) (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

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

\( 3 x-2 y=7 \) (1) \( y+2 y=14 \) (2)

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) \( x=2 \)

4. Make \( c \) the subject of \( g=\frac{c+3}{4+c}-7 \)
