Let's denote Cindy's age which is unknown with X
We know that Cindy's age is 3 times her age 6 years ago.
6 years ago Cindy's age was the present age (X) - 6 : X-6
The fact that the present age is 3 times her age 6 year ago can be written as:
3*(X-6)
So, finally:
X=3*(X-6)
64
4 x 10 = 40
4 x 6 = 24
(40)+(24) = 64
Answer:
2.48 / 10 = 0.248
About $0.25 for each slice of cheese.
(5,4) simply substitute the values in! they work :) hope it helped
Sin(α+β)=sin(α)cos(β)+cos(α)sin(β)
sin(α-β)=sin(α)cos(β)-cos(α)sin(β)
