-2x - 6 < = 1
-2x < = 1 + 6
-2x < = 7...change the inequality sign when dividing by a negative number
x > = -7/2
x > = - 3.5
the one that does not satisfy the inequality is : -4...because it is less then -3.5
Answer:
1.Factor both the numerator and the denominator.
2.Write as one fraction.
3: Simplify the rational expression.
4: Multiply any remaining factors in the numerator and/or denominator.
Step-by-step explanation:
The answer is 74 years. do 11/3=3.67. Then 3.67x20 =73.4 and since that .4 is not a full year you would have to round up to 74
By using Nathan's expression, Mitchel should have received 2 1/4 pounds of lemon drops. By using Darren's expression, Mitchel should have received 2 1/4 pounds of lemon drops. The difference in the amount of lemon drops Mitchel should have received using Nathan's expression instead of Darren's expression is 0 pounds.
Answer:
5.6 days
Step-by-step explanation:
We are given;
Initial Mass; N_o = 25 g
Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)
k = 0.1229
Formula is given as;
N_t = N_o•e^(-kt)
Plugging in the relevant values;
12.5 = 25 × e^(-0.1229t)
e^(-0.1229t) = 12.5/25
e^(-0.1229t) = 0.5
(-0.1229t) = In 0.5
-0.1229t = -0.6931
t = -0.6931/-0.1229
t = 5.6 days
