Answer:
D. x < 3
Step-by-step explanation:
3x + 7 < 16
To solve, we have to isolate x.
Subtract 7 from both sides :
3x < 9
Divide 3 from both sides :
x < 3
Now in some cases, you could say that the inequality sign would switch, but this is only when you divide by a negative sign, so keep that in mind.
Answer: 120
3 x 108 = 324
3 x 102 = 204
so 324 - 204 = 120
i think its c (Im not 100% sure
it is the equation which you have to solve.
That's D.
A(t) is the amount as a function of the temperature t.
