Choices A and B are correct. To find the equivalent expressions, you would do the distributive property for the choices to
get rid of the parentheses. You would then see which choices match up with 15 - 5x. Hope this helps!
A.) -5x + 15 (yes)
B.) 15 - 5x (yes)
C.) -15 + 5x (no)
D.) 5 - x (no)
₆C₃ is a combination. you can find this setting in the statistics menu of your scientific calculator (i think).
If you don't have a scientific calculator, you can use the following formula:

Answer: B
Answer:
The answer is below
Step-by-step explanation:
An equation is a mathematical statement that shows the equality between two expressions.
From the table, the average weight of the hamster at birth is 2 grams. The average weight of gerbil at birth is 2/3 of that of hamster. Let g represents the weight of the gerbil at birth, hence the weight can be gotten by solving the equation:
2/3 of hamster weight at birth = Average weight of gerbil at birth
2/3 × 2 grams = g
g = 2/3 × 2 grams = 4/3 grams = 1.33 grams
The average weight of gerbil at birth = 1.33 grams
Answer:
The rate of change of population is 16.69%.
Step-by-step explanation:
Rate of increase is defined as the ratio of difference of quantity increased by the original quantity multiplied by 100
that is ...........(1)
To find the rate of increased population of t town from 47,230 to 55,112
Here, original population = 47,230
Increased population = 55,112
Put the values in (1),
(approx)
Thus, the rate of change of population is 16.69%.
