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
Steps to solve:
x^3 - 125 = 0
~Add 125 to both sides
x^3 = 125
~Take cube root of both sides
x = 5
Best of Luck!
Answer:
<h2>
45°</h2>
Step-by-step explanation:
they are opposite angles, same value of 45°
Answer:
Note that it is not a perfectly elastic result so it is <em>irrational</em><em> </em>
Those two angles are alternate interior angles, so they must be congruent.
3x = 2x + 20
x = 20
