Answer:
45 horseshoe crabs and 45 sea stars
Step-by-step explanation:
The aquarium initially contained x crabs and x sea stars.
"After 15 horseshoe crabs and 27 sea stars are removed the ratio of horseshoe crabs to sea stars is 5:3"
(x-15):(x-27) = 5:3
(x-15)/(x-27) = 5/3
3(x-15) = 5(x-27)
3x-45 = 5x-135
90 = 2x
x = 45
C is the answer for the question
Answer:
4.4
Step-by-step explanation:
The mean is the sum of the data divided by the number of data values. so add them all together and then divide by how many numbers you added together.
Here is an example 1,3,4,5,7 so add 1+3+4+5+7=20 then you divide 20 by 5 and the mean is 4 for this example.
We have the following function:
f (x) = 2a ^ 2b + 3a ^ 3b ^ 2 + 2a ^ 2b ^ 4
We note that the function depends on x because it is f (x).
However, there is no variable x in the function.
Therefore we can assume that the function is constant, since:
a = constant
b = constant
Therefore, the degree of the function is zero
Answer:
The function is zero degree.
Answer:
x = 8
Step-by-step explanation:
180 = 78 + 94 + x
180 =172 + x
-172 -172
18 = x
