Answer:
1914
Step-by-step explanation:
Let the estimated total population of the deer =x
Out of x, 638 were tagged.
Out of 105, 35 were marked.
Expressing this as a ratio of the total to tagged, we have:
x:638=105:35
Therefore, the total deer population in the area is approximately 1,914.

B would be the answer
Answer:
substitute -10 for x and -20 for y
-10-20 / -20
-30/-20
1 1/2
Answer: The choice will be any equation where the slope is the same and the y-intercept is different.
Step-by-step explanation: Using slope-intercept form, y = mx + b,
m is the slope, b is the y-intercept.
Parallel lines will have the same slope.
So, you are looking for another equation that has 5/6 as the coefficient of x.
It could be an equation in the form 6y + 5x = _b_ where the constant, b, could be anything except -42, as that would be an identical line, not parallel.
Answer:
15 nickels were there with Alexis
Step-by-step explanation:
Let there be x nickels
given that
The number of dimes is 5 less than twice the number of nickels.
no of dimes in terms of x = 2*number of nickels - 5 = 2x - 5
we know that
value of 1 nickel = 5 cents
then
value of x nickel = 5*x cents = 5x cents
we know that
value of 1 dime = 10 cents
then
value of 2x-5 dime = 10(2x - 5) cents = 20x - 50 cents
Total value of x nickel and 2x -5 dimes = 5x + 20x - 50 = 25x - 50
given that
Alexia has total of $3.25 in nickel and dimes thus 25x - 50 must be equal to $3.25
$1 = 100 cents
$3.25 = 3.25 * 100 cents = 325 cents
Thus,
25x - 50 = 325
25x = 325 + 50 = 375
x = 375/25 = 15
Thus, no of nickels = x = 15 answer
