Answer:
The scanning electron microscope
Step-by-step explanation:
The scanning electron microscope can determine the proximity to a discharging firearm and/or the contact with a surface exposed to GSR
(x+13)2.3 if simplifying.
sum means add. so x plus 13 times 2.3 or 2.3(x+13)
0, 1, 2.
5 - 3x <= 7
-3x <= 2
x >= -2/3 (the inequality sign flips as we are dividing by a negative value)
4x + 1 < 13
4x < 12
x < 3.
So the integer values satisfying the inequalities are>
