Answer:
Benny would have 1/3y CDs.
Step-by-step explanation:
In order to find this, we know that Richard has 3 times the amount of CDs Benny does. Therefore, conversely, we must know that Benny has 1/3 of the CDs that Richard does. Knowing that Richard has y CDs allows us to model the amount for Benny as 1/3y.

Answer:
Csc(0)
Step-by-step explanation:
in trigonometry, the basic functions are Sine , Cosine and Tangent. Other functions such as Cotangent, Secant and Co secant are derivatives of these 3.
We know that
Csc Ф = 1/Sin Ф
Cot Ф = 1/tan Ф = cos Ф/ sin Ф
hence cos(0) csc(0)/sin(0)cot(0)
= cos Ф * 1/sin Ф ÷ sin Ф *cos Ф / sin Ф
= cos Ф/sin Ф * 1/ cos Ф
= 1/ sin Ф
= Csc Ф
Answer:
Step-by-step explanation:
there are two ways to solve systems of equations, elimination or substitution, this looks like elimination would work quickly
x= 25 -y
x + y = 25 (eq 1)
5x + y = 10 (eq 2)
subtract 2 from 1
x + y = 25
-(5x + y = 10)
-4x + 0y = 15
-4x = 15
x = - 15/4
now plug in x into either starting equations and solve for y
-15/4 + y = 25
y = 25 + 15/4
y = 100/4 + 15 /4
y = 115 /4
y = 28 3/4
we have solved it :)
