Inequalities are used to represent unequal expressions
The solution to the system of inequalities is (-1,1)
<h3>How to determine the solution</h3>
The system of inequalities is given as:
y > x + 2 and
y < 2x + 3
To do this, we start by plotting the graphs of the two inequalities
y > x + 2 and y < 2x + 3
See attachment for the graph
From the attached graph, both lines meet at (-1,1)
Hence, the solution to the system of inequalities is (-1,1)

Answer:
140 ml is needed to give 10.5g of Gantrisin
Step-by-step explanation:
In this question, we are asked to calculate how many milliliters liters will give a certain mass of Gantrisin.
Firstly, from the first values given, we can calculate the value if the density of the liquid.
Mathematically, the value of the density can be calculated by ;
Density = mass/volume = 1.5g / 20ml = 0.075 g/ml
Now for the second part of the question, we have the mass, but we do not know the volume. We can use the calculated density to know this.
We use the formula
volume = mass/density
Volume = 10.5g/(0.075g/ml)
Volume = 140 ml
